Abstract

An electronic design automation (EDA) editing tool usually comprises a Layout editor, a Schematic editor and a Symbol editor. In the designing process of an integrated circuit (IC), pre-designed units which are often used to conduct instantiation, for instance, in the editing process of a layout, a unit standard cell is invoked to create an Instance in a current editing unit, in the process of the instantiation, Library, Cell, View and parameter information of an instantiation current unit need to be defined, and due to the fact that the quantity of instances of generated devices is large, cells which are invoked frequently for use are only several common devices. However, in the creating process of the Instance, creating operation are often conducted in different units alternately. In the creating process of the Instance, the Library, the Cell, the view, the parameter information and other information need to be defined repeatedly, and a large quantity of tedious repeated manual labor exists. Therefore, the invention provides a method which is the method for generating devices rapidly, namely the method that shortcut device icons corresponding to commonly used devices are generated is utilized, and therefore invoking efficiency of the commonly used devices can be effectively improved, layout designing efficiency and schematic diagram designing can be greatly improved, and as a result, work efficiency of a designer can be improved.

Description

A kind of method of quick generation device

Technical field

The quick method that generates device is the method for the quick generation device in the EDA design field.The invention belongs to the EDA design field.

Background technology

The EDA edit tool generally comprises domain (Layout) editing machine, schematic diagram (Schematic) editing machine and Symbol editing machine.

In the IC design process, usually need to customize in advance some standard blocks, perhaps more pre-defined variable element device cells, in the specific design process, need to use these pre-designed unit to carry out instantiation, such as in the layout editing process, calling a unit standard block creates an example (here we claims that this example is Instance in current edit cell, the Instance that mentions in follow-up all refers to the example of call unit), because it is many to generate device instance number amount, and in the time of most of, the unit that is called that often uses is a few common device, and the frequency of utilization of these devices is very large, meets the Pareto Law of computing machine circle, namely 80 percent unit frequency of utilization is 20 percent, and other 20 percent unit frequency of utilization is 20 percent.In usually creating the Instance operation, the user at first needs to specify the design library (Library) of the unit that is called, unit (Cell), view (View) information, for parameterized units, need to specify simultaneously the parameters information of current example, owing in the different units of being everlasting, hocket in the process of establishment Instance, namely created after the Instance of A unit, may need to create again the Instance of B unit, then create the Instance of C, and then create again the Instance of A.In this process, need repeatedly to specify Library, Cell, there are a large amount of loaded down with trivial details repetition manual labors in View, and the information such as parameter.Therefore here we have proposed a kind of method: fast generate the method for device, can effectively improve design efficiency.

Here introduce first a key concept: basic device cell is the primary element that forms integrated circuit, mainly contains metal-oxide-semiconductor, semiconductor diode, semiconductor triode, resistive element, capacity cell, inductance element.

Generate in the device operation quick, use quick device icon mode to record the Library that is created the unit, Cell, View, and the information such as parameter.When the user clicks the Library that this icon can index appointment, Cell, View, and the information such as parameter, and automatically insert corresponding Library, and Cell, View and parameter information will improve the efficient that creates Instance greatly.Can effectively improve the efficient of calling of commonly using device to the mode of the corresponding quick device icon of device generation commonly used, can greatly improve layout design, principle diagram design efficient, and then can improve deviser's work efficiency.

Summary of the invention

The present invention proposes a kind of method of quick generation device, this method is according to system's predefined profiles, or user-defined configuration file can generate quick device icon, the direct device that uses these icons can generate fast correspondence in creating the Instance process.

Basic thought: quick device icon is divided into two kinds, and is a kind of in the inner definition of program (being called predefine herein), a kind of (being called self-defined herein) fully defined by the user.Generate in the quick device icon process according to predefined internal data format, at first read predefined internal data format, parse predefined device cell and type of device, type of device determines which kind of editing machine the quick device icon of current increase is applied in, such as in layout editor only loading type be the quick device icon of predefine of domain, then automatically set up the index of quick device icon and predefine device cell, in subsequent operation, click these icons and can find corresponding predefine device cell according to index.Self-defining quick device icon generates according to user-defined configuration file, at first edit configuration file by the user, specify devices unit information and type of device information, system can parse user-defined device cell and type of device automatically according to user-defined configuration file, automatically produce quick device icon, set up simultaneously automatically the index of new quick device icon and User Defined device cell, the User Defined device cell that these icons of click can find needs to call according to index in subsequent operation.

The setting of display icon symbol in the quick device icon, at first can define altogether its use of icon commonly used in internal system, for self-defined quick device icon, if the user has specified the icon of discrete cell, the icon that provides of user then, otherwise automatically specify an icon by system.All there is corresponding icon for predefined quick device icon.

The implementation step:

In conjunction with a concrete example automatic generation method of quick device icon is described, the operating process step is as follows:

1) prepares device cell, produce the commonplace components unit or use the mode of variable element unit to produce basic device cell by editor's commonplace components unit mode;

2) device cell according to configuration file format and preparation arranges quick device icon configuration file, and such as Fig. 1, Fig. 1 is the configuration file of an acquiescence;

3) open the EDA edit tool, will produce two quick device icons according to above the setting, as shown in Figures 2 and 3;

4) click to create the icon of Instance, will call and create the Instance order and insert Library, Cell, View, and the information such as parameter, as shown in Figure 4; Affirmation can create the example that calls for the unit, namely generates Instance;

5) use default parameters to generate Instance as shown in Figure 5;

6) use the Instance of custom parameter generation as shown in 6.
