Description

Device, method and system for processing printing information in chip EDA simulation

Technical Field

The invention relates to the technical field of chip simulation, in particular to a device, a method and a system for processing printing information in chip Electronic Design Automation (EDA) simulation.

Background

In the field of IC design, mainstream Chip design is more and more prone to System on Chip (SoC) design using a reusable IP core (also referred to as an IP module), and the SoC Chip is a highly concentrated embedded System on Chip, which can improve Chip design efficiency and shorten design cycle. In the development and design process of the SoC chip, EDA (Electronic design automation) simulation verification needs to be performed on system functions of the chip, wherein simulation verification on an IP module of the chip is an important link in the chip simulation process, common IP modules such as a CPU module, a DDR module, a USB module, an AXI module, an AHB module, a PCIE module and the like may be verified and debugged by different verification engineers. In the process of verifying and debugging the IP module, a verification engineer in charge of the module usually adds a print command of related information to a simulation file to obtain simulation related information (including various simulation process information, simulation result information, and the like) more intuitively in order to debug and trace simulation information. According to the print command in the simulation file, the print information is output to the display for displaying, and the function (or print function) of adding the print information in the simulation file is the most common way. For example, in an EDA simulation tool, print commands are usually from functions such as $ display (), "uvm _ info () in files such as verilog, systemverilog, etc., and the $ display statement is used for display output of system information (such as character string, simulation time, etc.) and will automatically change lines after each $ display execution; the function of the "uvm _ info statement is similar to that of the $ display statement, but the function is more powerful, and a redundancy threshold of the print information can be set to control the output of the print information.

At present, the verification environment of the SoC chip is usually maintained by multiple persons, and in the simulation process, each person can add printing information in a simulation file corresponding to the verification environment according to own simulation requirements, and all the added printing information can be output. For example, a verification engineer in charge of verifying the DDR module may add printing information related to the verification and debugging of the DDR module in the verification environment to know the real-time simulation process, and a verification engineer in charge of verifying the USB module may also add printing information related to the verification and debugging of the USB module in the verification environment to know the real-time simulation process. In the process of EDA simulation verification of a large SoC chip, verification debugging of a plurality of IP modules is included, and a plurality of verilog and system verilog simulation files are also included, and printing information in the plurality of simulation files not only causes information redundancy, but also influences the simulation progress. For example, a verification engineer in charge of verifying the DDR module adds related print information X in a verification environment, the verification engineer in charge of verifying the USB module adds related print information Y when performing simulation verification of the USB module, and since the simulation of the USB module calls the DDR module, the verification engineer of the USB module receives not only the print information Y of the USB module but also the print information X of the DDR module during the simulation process, and when the simulation of the USB module calls other modules, the verification engineer of the USB module also receives the print information of the other modules, but the verification engineer of the USB module often only needs to use the print information of the USB module without using the print information of the other modules. The phenomenon is also very common when the actual simulation is carried out, not only is the hardware simulation load increased, but also the simulation process is slowed down, the simulation progress is influenced, meanwhile, the verification engineer can not accurately obtain the printing information required by the verification engineer, and a large amount of time resources of the verification engineer are wasted.

On the other hand, the prior art also discloses some output control schemes for the printing information aiming at the problems of redundant printing information and complicated printing output control operation in the software development and debugging process. For example, chinese patent application CN202010090890.5 discloses a data printing method: detecting a serial port input printing command by using a target thread, wherein the printing command comprises an instruction character string and a keyword; and determining a printing function corresponding to the instruction character string, and executing the printing parameters by taking the keywords as input parameters of the printing function. According to the scheme, the output is controlled by inputting the printing command through the serial port, and the printing output of the concerned variable can be flexibly controlled by combining the predefined printing function without additionally printing the statement, so that the complexity of code modification is reduced. However, in the above technical solution, the debugging personnel needs to define the printing function, such as the accurate reading function, the matching reading function, the detection reading function, the accurate writing function, and the like, and preset and store the corresponding relationship between the command character string and the printing function, so that the operation is complicated, and different debugging personnel may define various printing functions based on their own requirements and styles, which results in debugging and printing of different modules and different personnel in various styles, and is difficult to maintain and diagnose in the later period, and is particularly not suitable for the SoC chip simulation scene requiring multi-user co-maintenance.

In summary, as the design scale of the SoC chip is larger and larger, and the number of IP modules is larger and larger, how to control the printing information of the IP modules in the EDA simulation of the chip is an urgent technical problem to be solved.

The control of printing of the print information according to the present invention means control of display and output of the print information.

Examples

Referring to fig. 1, the invention provides a processing apparatus for printing information in simulation of a chip EDA. The apparatus 100 includes an information collection module 110, a command parsing module 120, and a print control module 130.

And the information acquisition module 110 is used for acquiring a printing control command input by a user in a command line, wherein the printing control command is used for configuring the printing information in the EDA simulation tool so as to control whether the printing information is displayed and output.

A command analysis module 120, configured to analyze the print control command to obtain a simulation file and IP module information to which print information to be displayed and output belongs, and a simulation file and IP module information to which print information not to be displayed and output belongs; the simulation files are arranged corresponding to the IP modules, and different IP modules correspond to different simulation files.

A print control module 130, configured to match, according to an analysis result of the command analysis module, the simulation files of the IP modules in the EDA simulation tool based on the regular expression, execute the print operation of the simulation file on the display terminal of the user after acquiring the simulation file information to which the print information to be displayed and output belongs, and annotate the print function in the simulation file after acquiring the simulation file information to which the print information not to be displayed and output belongs, so that the corresponding simulation file is not printed on the display terminal of the user. And the annotated printing statement corresponding to the printing function is retained in the simulation file with the annotation information and does not execute the printing operation.

The simulation file is preferably a simulation file based on verilog language or systemverilog language, and the printing function is a $ display function or a' uvm _ info function.

The IP module may be specifically a CPU module, a DDR module, a USB module, an AXI module, an AHB module, and a PCIE module.

In this embodiment, the print control command may specifically include a control command option and a file keyword. The control command options include at least a Log _ on option and a Log _ off option. The file keywords include a first file keyword and a second file keyword.

The first file keyword is used as an input parameter of a log _ on option and is used for configuring simulation file name information corresponding to the printing information to be displayed and output. And the second file keyword is used as an input parameter behind a Log _ off option and is used for configuring simulation file name information corresponding to the printing information which is not required to be displayed and output. The name information of the simulation files comprises the IP module information of the simulation files so as to distinguish the IP modules of the simulation files.

By way of example and not limitation, a user may enter a command in the command line as:

-log_on < file1 >

-log_off <file2 >

the information collecting module 110 collects the command information of the user and then sends the command information to the command parsing module 120. The command parsing module 120 parses the control command options and the file keywords in the commands, and obtains parsing results as follows: the printing information in the simulation file with the name of the simulation file containing the log _ on input parameter < file1> is normally printed, and the printing information in the simulation file with the name of the simulation file containing the log _ off input parameter < file2> is not printed. Then, the print control module 130 controls whether the print information is printed or not according to the analysis result of the command analysis module 120.

In a specific setting, the simulation file name information may be configured as a keyword in a simulation file name. At this time, the simulation file having the first file keyword in the simulation file name performs the printing operation, and the simulation file having the second file keyword in the simulation file name does not perform the printing operation. That is, the simulation files having the file names including the first file keywords are normally printed out, and the simulation files having the file names including the second file keywords are not printed out.

Alternatively, the emulated file name information is configured as a full name of the emulated file. At this time, the simulation file having the simulation file name of the first file keyword executes the printing operation, and the simulation file having the simulation file name of the second file keyword does not execute the printing operation. That is, the simulation file having the file name of the first file keyword is normally printed out, and the simulation file having the file name of the second file keyword is not printed out.

In this embodiment, the print control module may specifically include an annotation unit and a printing unit.

The annotation unit may be specifically configured to: and acquiring a second file keyword after a command log _ off option, matching the simulation file names of all IP modules in the EDA simulation tool based on a regular expression, and after acquiring all simulation files of which the names contain the second file keyword, annotating all printing functions corresponding to printing information contained in the simulation files on a display terminal of the user so as to control the printing sentences of the simulation files not to be displayed and output.

The printing unit may specifically be configured to: acquiring a first file keyword after a command log _ on option, matching the simulation file names of all IP modules in an EDA simulation tool based on a regular expression, acquiring all simulation files of which the names contain the first file keyword, and executing printing operation on the simulation files on a display terminal of the user so as to control the printing statement display output of the simulation files.

In a preferred embodiment, the simulation file name of each IP module may include the name and/or number information of the IP module, and the name and/or number information of the IP module is added to the corresponding simulation file name in a prefix manner. As a typical example, for example, the emulation file name of the USB module is usually prefixed by USB, the file name of the DDR module is usually prefixed by DDR, and the file name of the CPU module is usually prefixed by CPU.

In another implementation manner of this embodiment, the print control command may further include content keywords, and the control command options may further include a Log _ on _ word option and a Log _ off _ word option, where the content keywords include a first content keyword and a second content keyword.

The first content keyword is used as an input parameter of a log _ on _ word option and is used for configuring content information contained in the print information to be displayed and output, and at the moment, the content of the print information contains the executed print operation of the first content keyword. And the second content keyword is used as an input parameter behind a Log _ off _ word option and is used for configuring content information contained in the print information which is not to be displayed and output, and at the moment, the content of the print information contains the second content keyword, and the printing operation is not executed.

And analyzing the input parameters after the Log _ on _ word option and the Log _ off _ word option of the command by the command analysis module, and sending the analysis result to the printing control module.

At this time, the print control module is configured to: matching the printing sentences corresponding to the printing information in the EDA simulation tool based on the regular expression according to the first content keywords after the command log _ on _ word option, acquiring all the printing sentences containing the first content keywords in the printing information, and executing printing operation on the printing sentences on the display terminal of the user so as to control the display and output of the printing sentences; and matching the printing sentences corresponding to the printing information in the EDA simulation tool based on the regular expressions according to the second content keywords after the command log _ off _ word option, acquiring all the printing sentences containing the second content keywords in the printing information, and executing comment-off operation on the printing sentences on the display terminal of the user so as to control the printing sentences not to be displayed and output.

-log_on_word <word1>

-log_off_word <word2>

the information collecting module 110 collects the command information of the user and then sends the command information to the command parsing module 120. The command parsing module 120 parses the control command options and the content keywords in the commands, and obtains parsing results as follows: normally printing the printing information containing the Log _ on _ word parameter < word1> in the printing content, and not printing the printing information containing the Log _ off _ word parameter < word2> in the printing content. Then, the print control module 130 controls whether the print information is printed or not according to the analysis result of the command analysis module 120.

The print control process of the present embodiment is described in detail below with reference to fig. 2 and 3.

When a USB verification engineer (i.e. a user) calls the DDR module when simulating the USB module, and the USB verification engineer wants to receive print information of the simulation file from the USB module but not receive print information of the simulation file from the DDR module, and wants to receive print information of the simulation file which is successfully tested but not receive print information of the simulation file which is failed to be tested, the USB verification engineer may input the following print control command through a command line:

-log_on usb*

-log_off ddr*

-log_on_word success

-log_off_word fail

the command parsing module parses 4 control command options "log _ on", "log _ off", "log _ on _ word", and "log _ off _ word" in the aforementioned commands and their corresponding file keywords or content keywords, respectively, as shown in fig. 2.

The analysis result obtained by the command analysis module is shown in fig. 3: controlling printing information in all simulation files (the simulation file name of the USB module comprises a prefix USB) under the USB module to be printed normally, and controlling printing information in all simulation files (the simulation file name of the DDR module comprises a prefix DDR) under the DDR module not to be printed; and controlling the printing information containing the keyword success in the printing content to be printed normally, and controlling the printing information containing the keyword fail in the printing content not to be printed.

The print control module 130 controls whether the print information is printed or not according to the analysis result of the command analysis module 120. Specifically, after acquiring an input parameter "USB ″" of the log _ on command, the printing unit of the print control module 130 matches the simulation files of the IP modules in the EDA simulation tool based on the regular expression, and after acquiring all the simulation files with file names beginning with USB, controls the print information of these simulation files to perform the printing operation, as shown in fig. 3, the print information in the simulation files with names beginning with USB in the table (including USB _1.V, USB _2.V, \8230;, USB _ n.v, where n is an integer greater than 1) is normally printed on the display terminal of the USB verification engineer. After obtaining the input parameter "ddr" of the log _ off command, the annotating unit of the print control module 130 matches the simulation files of the IP modules in the EDA simulation tool based on the regular expression, and after obtaining all the simulation files with file names beginning with ddr, annotates the function statements such as the print functions $ display (), "uvm _ info (), i.e., annotates the print functions with annotation symbols. After the print function is annotated, the corresponding print statements are not run but are kept in the simulation files as annotation information, so that the print information of the simulation files can be controlled not to be printed and output in the display terminal of the USB verification engineer, as shown in FIG. 3, the print information in the simulation files (including ddr _1.V, ddr _2.V, \ 8230; \8230;, ddr _ m.v, < m > 1 integer) with the names ddr in the table is not printed and displayed in the display terminal of the USB verification engineer.

Meanwhile, after acquiring the input parameter "success" of the log _ word _ on command, the printing unit of the printing control module 130 matches the printing information in the simulation file of each IP module in the EDA simulation tool in the regular expression manner, and after acquiring the printing statements including "success" in the printing information, controls the printing statements to be printed and output, as shown in fig. 3, the printing information "Test success" in the file1.V simulation file in the table includes "success", and the printing information of the simulation file is normally printed in the display terminal of the USB verification engineer. After acquiring the input parameter "fail" of the log _ off _ on command, the annotating unit of the print control module 130 matches the print information in the simulation file of each IP module in the EDA simulation tool in a regular expression manner, acquires the print statement including "fail" in the print information, annotates the print function in the simulation file, and after the print function is annotated, the corresponding print statement will not run but will be retained in the simulation file as the annotation information, as shown in fig. 3, the print information "Test fail" in the file2.V simulation file in the table includes "fail", and the print information in the simulation file is no longer printed and output in the display terminal of the USB verification engineer.

Therefore, when the verification engineer simulates, the printing information in the simulation files can be flexibly configured according to needs, so that the printing information of some simulation files is not required to be output, and the printing information of other simulation files is normally output. In particular, the verification engineer can flexibly control the output of relevant printing information and the non-output of non-relevant printing information based on the IP module in charge of the verification engineer, the operation is simple and flexible, the printing information is accurate, and time resources and computing resources for modifying and compiling a code file for controlling the output of the printing information are saved.

The invention further provides a method for processing the printing information in the simulation of the EDA of the chip.
