In concurrent transaction level modeling, if carry out appropriate design to partial model, it can be made to have reusable characteristic, briefly, be exactly the information that this partial model does not comprise system-level model, in outside be exactly one and receive input signal, return " flight data recorder " of output signal.Based on this " flight data recorder ", the process of system-level modeling just only needs the connection describing these " flight data recorders ".

Fig. 3 is the matrix structure figure schematic diagram of the distribution mode of partial model provided by the invention, describes in detail below in conjunction with Fig. 1, Fig. 2 and Fig. 3.

Shown in Fig. 3 is the initial matrix of the two-dimensional grid of 5 × 5, wherein has two base part models: sample_m1 and sample_m2, sample_m1 represent processor, and sample_m2 represents internal memory.Different according to the type of partial model, this initial matrix can be divided into several submatrix block: N1, N2 and N3.Wherein N1 forms the matrix of 3 × 3, and matrix-block N2 forms the matrix of 2 × 3, and matrix N 3 forms the matrix of 5 × 2 respectively.

The reference representation storehouse set up in advance comprises:

The distribution formula of two-dimensional matrix is:

The annexation formula of the partial model of two-dimensional matrix distribution is:

i∈[0，N]，j∈[0，N]，

n∈N，l∈N，p∈N，v∈N，u∈N

The syntactic information of above-mentioned two formula comprises:

Algorithm comprises:

1, first by ltr and dig constructed variable (var), according to the rule (beginning of letter, after with any number of letter or digit) of var, Two Variables a1 can be constructed, a2.

2, construct numeral (num) by dig, according to the rule (digit starts, after with any number of digit) of Num, numeral 10 can be constructed.

3, by the definition (according to the combination of oper between numeral, variable or numerical variable) of formula (fom), can formula be obtained: a1+a2-10.

Three submatrixs as shown in Figure 3: N1, N2 and N3, illustrate for submatrix N1, for convenience of description, the abscissa herein in position coordinates and ordinate be not to have the <x of footnote, and y> represents.

Because submatrix N1 is 3 × 3, in the upper left corner of initial matrix, three row of the corresponding initial matrix of data of three row comprised and three row and three row.Abscissa x can get three values between 0 to 2, same, and ordinate y can get three values between 0 to 2, and three kinds of values of three of x kinds of values and y can combination in any, forms all positions in 3 × 3 matrixes.Therefore, the distribution and expression formula of submatrix N1 can be written as:

<x，y>，x＝i，y＝j，i＝[0，2]，j＝[0，2]。

<m，n>，m＝i，n＝j，i＝[3，4]，j＝[0，4]。

(position coordinates is respectively (2 to be positioned at tertial three partial models with submatrix N1,0), (2,1), (2,2) (position coordinates is respectively (3,0)), to be positioned at the 4th three partial models arranged with submatrix N3, (3,1), (3,2)) between annexation be example illustrate annexation express formula.

If the 3rd row first have annexation with first row first in submatrix N3 in submatrix N1, in submatrix N1, in the 3rd row second and submatrix N3, first row second has annexation, and in submatrix N1, the 3rd arranges the 3rd and have annexation with first row the 3rd in submatrix N3.Submatrix N1 is in the left side of initial matrix, and the 3rd row of submatrix N1 are the 3rd row of initial matrix, and submatrix N3 is on the right side of initial matrix, and the first row of submatrix N3 is the 4th row of initial matrix.Its annexation expresses formula:

R (< u, v >, < m, n >) = (\{\begin{matrix} u = 2 \\ v = i \end{matrix}, \{\begin{matrix} m = 3 \\ n = i \end{matrix}, i = [0,2])

In described connection formula, the span of v with n is consistent, therefore can represent with identical parameter i.

In described annexation expression formula, the part of numeral " 2 " and numeral " 3 " represents with predetermined syntactic information.Such as, dig::=0|3|, num::=dig ^*, so num representative digit " 3 ", DIG::=0|2|, NUM::=DIG ^*, NUM representative digit " 2 ", so above-mentioned annexation is expressed formula and is become:

R (< u, v >, < m, n >) = (\{\begin{matrix} u = NUM \\ v = i \end{matrix}, \{\begin{matrix} m = num \\ n = i \end{matrix}, i = [0,2])

Wherein, NUM and num is the parameter of the numeric type according to the syntactic information definition preset.

According to the syntactic information preset, check whether correctly distribution and expression formula and annexation express the grammer of formula, comprising: whether the spelling of parameter name is correct, and whether algorithm is correct.Such as: num is made up of one or more dig, and dig is Arabic numerals, as 3 is correct num, because it is made up of a dig, and 3b is illegal num, because it is not made up of dig entirely, then can feed back following error message:

Error：Line：6，3b?is?wrong.

Represent that the num spelling of the 6th row makes mistakes.

Check that distribution and expression formula and annexation express the logic of formula, comprising:

Check whether described annexation expression formula comprises the annexation of each partial model;

Check whether described annexation expression formula comprises the annexation of the redundancy of described partial model;

To check in described distribution and expression formula position coordinates and partial model whether one_to_one corresponding.

Such as, in the annexation expression formula that the annexation of partial model A does not comprise, then following error message can be fed back:

Erro：model?A?is?miss。

Represent the annexation having lacked partial model A.

If the syntactic information that described distribution and expression formula and annexation express formula is correct and logically true, then generate description document.Described description document comprises position coordinates and the annexation of described partial model, and described annexation is with the Name & Location coordinate of source partial model, and the Name & Location coordinate of destination partial model represents.Described position coordinates and partial model are one to one, and therefore described position coordinates is the mark of described partial model, with the partial model that described position coordinates representative is corresponding with it.

Annexation between partial model A and partial model B, can show with the form of text description, such as, [partial model A: the mark <2 of source partial model, 1>, partial model B: the mark <3 of destination partial model, 1>], this represents to have annexation between partial model A and partial model B, A is the title of source partial model, it is designated <2, 1>, the title of end pieces model for the purpose of B, it is designated <3, 1>, also can with program code, the form performances such as graphic symbol, such as, code form: R (modleA<2, 1>, modleB<3, 1>), R represents to have annexation between partial model modleA and partial model modleB, modleA is the title of source partial model, its position coordinates (mark) is <2, 1>, the title of end pieces model for the purpose of modleB, its position coordinates (mark) is <3, 1>.

Annexation between partial model can be classified, and generally has two kinds: unidirectional connection and be bi-directionally connected relation.Such as, be unidirectional annexation between partial model A and partial model B, represent that partial model A is to the unidirectional transmission message of partial model B or event content, or partial model B be to the unidirectional transmission message of partial model A or event content; Be be bi-directionally connected relation between partial model A and partial model B, represent that partial model A sends message or event content to partial model B, and partial model B also send message or event content to partial model A.

The number of the annexation between partial model and the type of annexation also can add in described description document.Such as, R (modleA<2,1>, modleB<3,1>) represent between modleA and modleB it is be bi-directionally connected relation, S (modleA<2,1>, modleB<3,1>) represent the unidirectional annexation of modleA to modleB.R (modleA<2, 1>, modleB<3, 1>), R (modleA<2, 1>, modleC<4, 1>), R (modleA<2, 1>, modleD<5, 1>), represent modleA respectively with modleB, modleC, modleD has the relation of being bi-directionally connected respectively, and modleA has 3 annexations.ModleA has the relation of being bi-directionally connected respectively with modleB, modleC, modleD respectively, and modleA has 3 annexations also can be kept in description document.

Because different concurrent transaction level model implementation method is different, the method for expressing of the design's not limiting part model.Described description document is applicable to the paralleling transaction level modeling method of various system and partial model loose coupling.The description document generated can time for the system model coded description of physical simulation device, also can be the texts such as txt, word.

S21, generates the description document of concurrent transaction level simulation system;

S22, the title of obtaining communication source, described communication source is source partial model to be established a communications link;

S23, searches the title of the communication objective end corresponding with described communication source in the description document of described concurrent transaction level simulation system, and described communication objective end is the destination partial model corresponding with source to be established a communications link;

S24, record communication port information, described communication port information comprises the Name & Location coordinate of described communication source, the Name & Location coordinate of communication objective end;

In the modeling or design process of the concurrent transaction level simulation system of reality, the structure of partial model is very complicated, and described partial model comprises communication module, also comprises component logic, in order to realize logic function.

Described communication module comprises port router (also claiming router), communication controler and port queue administration module etc., and port queue administration module is generally used for setting up communication port according to communication port information.Port router comprises routing iinformation administration module, and described routing iinformation administration module comprises routing table cache module, enquiry module etc.Communication port comprises port arrangement module, message transmission module, message processing module etc.

Port queue administration module obtains the port number of this partial model from enquiry module, and obtains the communication port information of each port successively.Annexation between partial model generally has three kinds: communication port generally can be divided into three types: only send the communication port of message, receive only the communication port of message or event content, has not only sent but also the communication port of receipt message or event content.The type of communication port and number are generally by type and the decision of the annexation of this partial model.Such as, partial model A and partial model B, partial model C, partial model D have the relation of being bi-directionally connected respectively, and so partial model A has three communication port, and this communication port is not only sent but also the communication port of receipt message or event content.If partial model A is to the unidirectional transmission message of partial model B, then partial model A has the communication port that only sends message, and partial model B has the communication port that receives only message or event content.

A communication port has a communication port information, and that is, the number of communication port information is consistent with the number of communication port.After port queue administration module obtains each new communication port information, by communication port new for establishment one in communication module, by numeral or this communication port of letter designation, and corresponding communication port information is inserted port information administration module.

Type, the number of the annexation of partial model generally also can be included in description document, and the title of communication port is generally defaulted as numeral or letter in addition, when generating description document, can be included in description document by auto-sequencing.

Fig. 5 to Figure 18 is the detailed applications method of the description document provided in the embodiment of the present invention, described description document is also referred to as topological structure description document, in the present embodiment, the communication module of partial model sets up communication port according to communication port information, correspondingly, also comprise the port information (as title, mark etc.) of partial model in description document, communication port information also comprises the communication port information of source and the port information of communication objective end.Describe in detail below in conjunction with Fig. 5 to Figure 18.

Fig. 5 is the structure list of the topological structure description document that the embodiment of the present invention provides, and the structure of topological structure description document as shown in Figure 5.Topological structure description document is main unit with partial model, describes the essential information of each partial model, and the annexation of the port of this partial model.In order to avoid a conflict, topological structure description document requires that being designated of partial model is overall unique, and the title of the port of partial model is unique in this partial model.Because being designated of partial model is overall unique, the title of port only needs to ensure that partial model is interior unique, carries out would not making a mistake when topological structure describes to this port.

Partial model is generally transmitting terminal or the receiving terminal of message, and therefore partial model can be used as communication source or communication objective end.For convenience of description, if indicate without special, in following content, communication source or communication objective end is namely represented with partial model.

What this topological structure description document described is annexation between partial model, and point out the annexation between the port of a partial model and the port of miscellaneous part model.

As shown in Figure 5, the annexation of the port of the whole partial models comprised in a concurrent transaction level simulation system is represented.Comprise the annexation of the port of several partial models in this topological structure description document, each partial model comprises two parts content, and one is module information M1, and two is channel information M2.In module information M1, comprise the title of partial model, mark, type and number of active lanes, type is generally finger processor, internal memory, hard disk etc., and number of active lanes is the number of the communication port between this partial model and miscellaneous part model.In channel information M2, itemize have recorded the information of each port, the port information of a port recorded in every bar record, comprise the mark of the partial model having annexation with this port, title, have annexation with which port of this partial model, the title of this port, type, time of delay.The title of port is generally defaulted as Arabic numerals or letter, and according to numeral or the sequence of alphabetical order.Port type generally comprises transmission types, type of receipt and transmission and to hold concurrently type of receipt.Refer to that this port sends a message and how long needs time of delay.

Such as, partial model A has 4 ports, and the title of 4 ports is respectively a, b, c, d, and has 4 communication ports between partial model A and miscellaneous part model.The module information of partial model A comprises, and the name of partial model is called A, is designated <2, and 1>, type are processor and number of active lanes is 4.Channel information comprises 4 records, the information of a port recorded in every bar record, if port a is in order to initiate a message, (<3 is designated with partial model B, port f 1>) has communication connection, then the record of port a comprises: the mark <2 of source, 1>, destination be designated <3,1>, the port name of source is called a, and the port name of destination is called f, channel type is transmission types, and time of delay is 0.04s.

The general communication connection according to concurrent transaction level simulation system to be simulated of topological structure description document, sets up the annexation of source and destination.When establishing a connection, the type of the port of described source is transmission types, then the type of the port of corresponding with it destination can only be to be type of receipt or to receive transmission types of holding concurrently, and same partial model both can be source also can be destination.

According to the annexation between each partial model of concurrent transaction level simulation system to be simulated, annexation in described topological structure description document between analog component model, after partial model obtains described topological structure description document, according to content wherein, set up the annexation between partial model, then achieve the modeling of concurrent transaction level simulation system.

The analogy method that the topological structure description document of step S101 can utilize setting up shown in Fig. 1 to communicate between partial model generates, and described source is the partial model that the issuing side of message initiates a message in other words conj.or perhaps, and the port of described source is in order to send described message; Described destination is the receiving terminal of described message or perhaps the partial model of receipt message, and the port of described destination is in order to receive described message, and namely source and destination have annexation.Because the transmission of message moves in circles with reception, the source of therefore message transmission, also can be the destination of message sink, in other words, source and destination can change according to the flow direction of message next time.In concurrent transaction level simulation system, partial model normally communicates source or communication objective end.

Described communication source is source to be established a communications link, the partial model namely in concurrent transaction level simulation system.After partial model has designed, set up the communication connection between partial model, the more parallel host network of configuration, concurrent transaction level simulation system just completes.For preventing in the process established a communications link, occurring situation about missing, the partial model designed, when establishing a communications link, regard this partial model as source to be established a communications link.

The port of described communication objective end is the port of the destination corresponding with the port of source described to be established a communications link, and described communication objective end is the destination corresponding with source to be established a communications link.Message is flowed by port in the entire system, when establishing a communications link, need to determine the communication source of message and communication objective end, guarantee that both are corresponding, then determine which port of communication source is corresponding with which port of communication objective end, ensure that message flows in the port of correspondence.

Be that described communication source and communication objective end set up communication port and after configuration communication passage based on described communication port information, communicate in the communication port set up for communication source and corresponding communication port information the port of source, the port of the communication port set up for communication objective end and corresponding communication objective end.Message is sent to communication objective end by the communication communication port of source, the communication port of configuration, and the communication port of communication objective end receives the message (will be described in detail follow-up to the parsing of message) after resolving.

Generally, transmission types port and type of receipt or to receive the port of transmission types of holding concurrently corresponding; The port of type of receipt and transmission types or to receive the port of transmission types of holding concurrently corresponding; Send the port of type of receipt of holding concurrently, if send message, then identical with the port of transmission types, if receipt message, then identical with the port of type of receipt.

Topological structure description document comprises module information and the channel information of this partial model, wherein module information comprises the title of this partial model, mark, type and number of active lanes, and number of active lanes is the number of the communication port between this partial model and miscellaneous part model.In channel information, itemize have recorded the information of each port, comprises the mark of the partial model having annexation with this port, title, has annexation, the title of this port, type, time of delay with which port of this partial model.

In S104, record communication port information, these information selectively can be recorded according to actual conditions, communication port information only records the information of conventional port under normal circumstances, can save memory space like this.

Described communication port is used to transmission message, and communication port is generally by parallel host real-time performance.

After concurrent transaction level simulation system starts, communication module A3 will configure automatically.First port router A1 will read topological structure description document, be kept in routing table cache modules A 112 by the topological structure description document read, and form route-caching table.Then enquiry module A12 searches the title of the port of the communication objective end corresponding with the port of described communication source and the mark of communication objective end in route-caching table.

Communication module A3 using the partial model belonging to oneself as communication source, from the communication port information that port router A1 acquisition is corresponding with the port of described communication source, and set up based on described communication port information the communication objective end configuration communication passage that communication port is also communication source and correspondence.Specifically, port queue administration module A32, is inquired about by the enquiry module A12 in port router A1, obtains the communication port information that communication module A3 needs, and sets up communication port A2 based on described communication port information.Communication port information comprises the mark of destination, the title of the port of destination, and the type of this port is single transmission, reception or transceiver port.Communication port information will be kept in the port information administration module A26 of each communication port.Port queue administration module A32 obtaining communication port information, therefrom determines to need to set up several communication port.

Port arrangement modules A 21 finds the communication mark of source and the mark of communication objective end from communication port information, configuration communication port between the two.When component logic A4 needs to send message, need by communication port, message is sent to communication objective end from communication source.Communication port is generally rely on parallel host real-time performance, sends message, also can regard as and send message by parallel host network by communication port.

Message transmitting process as shown in figure 12, when component logic A4 outwards sends message by communication port A2, only needs to indicate to use which communication port, without the need to providing this port connection in systems in which.As shown in figure 12, the event bag that component logic A4 sends only comprises " title of transmit port " and the most substance of " event content " two, the title of the communication port of " title of the transmit port " source that namely communicates.When event bag enters communication module A3, first will carry out Message Processing by communication controler A31, communication controler A31 resolves message, obtains " title of transmit port " and " event content ".After port queue administration module A32 obtains the control of respective communications port, the event bag after resolving is temporarily stored in message transmission cache module A24.The control obtaining respective communications port refers to, whether idlely monitors this port, when this port is idle, controls this port and sends message.Message transmission module A22, when external communication port is idle, sends cache module A24 from message and takes out an event bag, and the communication port information adding corresponding port according to " title of transmit port " forms message.Generally, for event bag increases " mark of communication source ", " title of the port of communication source ", " mark of communication objective end ", " title of the port of communication objective end " four fields, based on the content of these four fields, message can send in parallel host network A 61.

First the receiving course of message as shown in figure 13, after the partial model that the message sent by communication source is arrived as communication objective end by the host network A 61 that walks abreast, will pass to communication controler A31, be resolved the message received by communication controler A31.Now message comprises communication port information and the event content of the port of the communication source sending this message, comprise particularly " mark of communication source ", " title of the port of communication source ", " mark of communication objective end ", " title of the port of communication objective end ", and " event content " five parts.According to " title of the port of communication objective end ", message bag is simplified as only having " title of receiving port " and " event content " two parts by port queue administration module A32, and obtain the control of corresponding receiving port, namely monitor this port, when this port is idle, control this port accepts.Wherein " title of receiving port " namely " title of the communication port of communication objective end ".Message after simplifying will pass to the message sink cache module A25 of communication port A2, and when this port is idle, pass to message processing module A23 process, result will be passed to component logic A4.

Figure 14 is the structure chart of a kind of execution mode of partial model provided by the invention, and Figure 15 is the structure chart of a kind of execution mode of concurrent transaction level simulation system provided by the invention.Describe in detail below in conjunction with Figure 14 and Figure 15.

Figure 14 is the structure chart of a kind of execution mode of partial model provided by the invention, and partial model A62 comprises: communication module A3 and component logic A4.Component logic A4, for sending event bag or receiving result.

Figure 11 is the structure chart of a kind of execution mode of concurrent transaction level simulation system provided by the invention, and concurrent transaction level simulation system A6 comprises partial model A62 and parallel host network A 61.

Each partial model A62 simulates the part in concurrent transaction level simulation system A6 independently, and carries out the transmission of message by parallel host network A 61.When needing to carry out mutual between partial model A62, will by parallel host network A 61 forwarding messages.When simulating concurrent transaction level simulation system A6, being realized by message mutual between two partial model A62, in message, comprising event content or event bag.Event bag is the packet of User Defined structure.In this packet, abstract realization is the event content of granularity with sequential between hardware module by user.

The interaction protocol that the process of interacting message adopts with partial model A62 is usually irrelevant, usually the details such as concrete bus timing are not related to, that is, component logic A4 sends or receives result, and communication module A3 is responsible for that event handbag is dressed up message and is sent by its communication port A2.Component logic A4 is indifferent to message and is sent by whom, is only concerned about to have issued what message, have received what result.Accordingly, communication module A3 is indifferent to transmission or have received what message, is only concerned about what who sent, whom sends to.Partial model A62 be divide into two parts by this, and component logic A4 is responsible for transmission event bag or receives result, and communication module A3 is responsible for sending or receipt message.During design part model A62, no longer be entangled with and which kind of need communicate to connect in concurrent transaction level simulation system, how annexation between partial model designs, during design concurrent transaction level simulation system, how the annexation be also no longer entangled with between partial model designs the communication connection that could meet concurrent transaction level simulation system.These annexations or communication connection are preset in topological structure description document, only need obtain this file, carry out the configuration of communication port according to the content of this file, just can meet the demand of the communication connection of concurrent transaction level simulation system, and also achieve the annexation between partial model.

This not only reduces the degree of coupling between partial model and concurrent transaction level simulation system, and improves the development efficiency of concurrent transaction level simulation system.If when the communication connection of the annexation between partial model or concurrent transaction level simulation system changes, only need corresponding content in amendment topological structure description document, then route cache table and communication port information are upgraded, just can complete the amendment of the communication connection of annexation between partial model or concurrent transaction level simulation system.This reduces the expense safeguarded partial model and concurrent transaction level simulation system, no longer needs to redesign partial model or concurrent transaction level simulation system, enhances the reusability of partial model, reduce the wasting of resources, saved cost.

Figure 16 is the communication connection schematic diagram of partial model in concurrent transaction level simulation system provided by the invention.Figure 12 is described in the correspondence between the partial model A62 of two parallel runnings in concurrent transaction level simulation system, omits and other structures herein.As shown in figure 16, communication module A3 mainly comprises: communication port A2, communication controler A31, port queue modules A 32, port router A1 for the structure of the communication module A3 of concurrent transaction level simulation and the applied environment in concurrent transaction level simulation system thereof.Port router A1 obtains outside topological structure description document.

Communication port A2 is connected with port router A1 by port queue modules A 32, can be obtained the information in port router A1 by port queue modules A 32.

As shown in figure 16, undertaken by communication module A3 alternately between two partial models, when component logic A4 needs to carry out PERCOM peripheral communication, first event bag will be passed to communication module A3, be responsible for event to encapsulate dress up message and forward by communication module A3; Equally, when receipt message, first the message received will be responsible for process by communication module A3, then pass to component logic A4.Under this scheme, component logic A4 is undertaken relying on communication module A3 completely with the mutual of outside, when not considering external condition, can realize the internal logic of partial model A62 independently, this design improves the development efficiency of partial model effectively.

Each partial model A62 can be divided into two parts, and a part does not relate to externally mutual component logic A4, and another part is responsible for the communication module A3 with outside mutual.Figure 16 is the structure chart of a kind of execution mode of event bag provided by the invention, and Figure 17 is the structure chart of a kind of execution mode of message provided by the invention.

Event bag B1 shown in Figure 17, comprises title B11 and the event content B10 of transmit port, and the title B11 of transmit port namely communicates the title of port of source.Event bag B1 is sent by component logic A4.Message B2 shown in Figure 18, comprises event content B10, the mark B12 of communication source, the title B11 ' of the port of communication source, the mark B13 of communication objective end, the title B14 of the port of communication objective end.The title B11 ' of the port of the source that wherein communicates is identical with the title B11 of transmit port in Figure 17.Message B2 is after receiving event bag B1 by communication module A3, adds that ingress port information formed, and is finally sent by communication port.

In sum, technical scheme disclosed in the embodiment of the present invention, improves the development efficiency of concurrent transaction level simulation system, reduces the expense safeguarded partial model and concurrent transaction level simulation system.
