Abstract

EDA edit tool generally comprises Layout editing machine, Schematic editing machine and Symbol editing machine.In IC design process, these pre-designed unit of frequent use carry out instantiation, such as in layout editing process, call a unit standard block and create an example in current edit cell, in instantiation process, need to specify Library, Cell, the parameter information of View and instantiation active cell, because generating device example quantity is many, and the frequent called unit used is a few common devices.And create in the process of Instance and hocket in different units of being everlasting.Need in this process repeatedly to specify Library, the information such as Cell, View and parameter, there is repetition manual labor loaded down with trivial details in a large number.Therefore we have proposed a kind of method here: the method for quick generating device, that namely the mode of corresponding for conventional device generation quick device icon can be improved conventional device effectively calls efficiency, greatly can improve the efficiency of layout design, principle diagram design, and then the work efficiency of deviser can be improved.

Description

A kind of method of quick generating device

Technical field

The method of quick generating device is the method for the quick generating device in EDA design field.The invention belongs to EDA design field.

Background technology

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

In IC design process, usually need to customize some standard blocks in advance, or more pre-defined variable element device cells, in specific design process, the unit using these pre-designed is needed to carry out instantiation, such as in layout editing process, call a unit standard block in current edit cell, to create an example (here we claim this example to be Instance, the Instance mentioned in follow-up all refers to the example of call unit), because generating device example quantity is many, and time most of, the called unit of frequent use is a few common devices, and the frequency of utilization of these devices is very large, the Pareto Law of according calculation machine circle, namely the unit frequency of utilization of 80 percent is 20 percent, and the other unit frequency of utilization of 20 percent is 20 percent.Usually creating in Instance operation, first user needs the design library (Library) of specifying called unit, unit (Cell), view (View) information, for parameterized units, need the parameters information of simultaneously specifying instant example, hocket in different units of being everlasting in process due to establishment Instance, namely after creating the Instance of A unit, the Instance creating unit B again may be needed, then create the Instance of C, and then create the Instance of A again.Need in this process repeatedly to specify Library, Cell, View, and the information such as parameter, there is repetition manual labor loaded down with trivial details in a large number.Therefore we have proposed a kind of method here: the method for quick generating device, effectively can improve design efficiency.

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

In the operation of quick generating device, quick device icon mode record is used to be created the Library of unit, Cell, View, and the information such as parameter.The Library specified can be indexed, Cell, View when user clicks this icon, and the information such as parameter, and automatically insert corresponding Library, Cell, View and parameter information, greatly will improve the efficiency creating Instance.What the mode of corresponding for conventional device generation quick device icon can be improved conventional device effectively calls efficiency, greatly can improve layout design, principle diagram design efficiency, and then can improve the work efficiency of deviser.

Summary of the invention

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

Basic thought: quick device icon is divided into two kinds, a kind of in program inside definition (being called predefine herein), one (being called self-defined herein) completely defined by the user.Generate in quick device icon process according to predefined internal data format, first predefined internal data format is read, 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 is 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 can find corresponding predefine device cell according to index.Self-defining quick device icon generates according to user-defined configuration file, first configuration file is edited by user, specify device cell information and type of device information, system can parse user-defined device cell and type of device automatically according to user-defined configuration file, the quick device icon of automatic generation, automatically set up the index of new quick device icon and User Defined device cell simultaneously, in subsequent operation, click these icons can find according to index the User Defined device cell needing to call.

The setting of display icon symbol in quick device icon, first it uses, for self-defined quick device icon, if user specifies the icon of discrete cell altogether to define conventional icon in internal system, then use the icon that user provides, otherwise automatically specify an icon by system.Corresponding icon is all existed for predefined quick device icon.

Concrete implementation step:

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

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

2) quick device icon configuration file is set according to the device cell of configuration file format and preparation, if Fig. 1, Fig. 1 are the configuration files of an acquiescence;

3) EDA edit tool is opened, will according to arranging the quick device icon of generation two above, as shown in Figures 2 and 3;

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

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

6) Instance using custom parameter to generate is as shown in 6.

Claims

1. a method for quick generating device, is characterized in that:

(1) in the quick generating device preparatory stage, produce commonplace components unit by editor's commonplace components unit mode or use the mode of variable element unit to produce basic device cell;

(2) generating in quick device icon process according to configuration file format, first configuration file is edited by user, after user preserves configuration file, system can parse user-defined device cell and type of device automatically according to user-defined configuration file, the quick device icon of automatic generation, legend is wherein specified by user, if user does not provide, system is then used to provide default icon, automatically set up the index of new quick device icon and User Defined device cell simultaneously, in subsequent operation, click these icons can find according to index the User Defined device cell needing to call,

(3) on shortcut bar, click different quick device icons, system according to the index relative set up before, its respective devices unit of automatic acquisition;

(4) create at the unit obtained according to quick device icon in the process of Instance, differentiation is needed to be commonplace components unit or basic device cell, if commonplace components unit, then the Instance that user directly can generate this unit in current design after clicking quick device icon calls; If the basic device cell of variable element, then, after user clicks shortcut icon, automatically insert parameter, generate Instance according to parameter and call.
