Design guiding system and method for circuit board layout rule

Abstract

The invention discloses a design guiding system and method for a circuit board layout rule. The system comprises a part database, an input module, a processing module, an editing module, a succession module and a layout rule database, wherein the part database is used for storing packaging specification information data and name naming rule of a circuit board element; the input module is used for inputting network name of a circuit board to be drawn and the packaging specification information data of the related circuit board element and is connected with the part database; the processing module is used for selecting a specific network name as well as related element and terminal element names from the network name and the packaging specification information data, wherein layout rules are to be set for the specific network name as well as the related element and terminal element names; the editing module is used for finding out a connection relation and defining the layout rule of a matching group according to the analyzed circuit board terminal element; by using the succession module, the user can succeed the edited layout rule document to other circuit boards with the same circuit architectures; and the layout rule database is used for storing and arranging the edited documents so as to fast and conveniently search and obtain the desired layout rule document so that the resources are convenient to be shared and fast succeeded.

Description

technical field [0001] The present invention relates to a design guidance system and method for circuit board layout rules, more specifically, a design guidance system and method for layout rules applied to circuit board wiring data. Background technique [0002] With the development of high-density integrated circuits, the demand for electronic design automation (EDA) software for circuit board layout is also increasing. Currently, the more commonly used software includes Allegro and Protel. [0003] When using these software to set layout rules, traditionally, the following two different input methods can be used to set the MatchGroup: [0004] Enter according to the network name (NetName); and [0005] Input according to the pin pair (PinPair). [0006] In the first input method based on the network name, since the user inputs the network name, the advantage is that it is easy to set and the complexity of the required auxiliary program is relatively low.

[0009] However, the disadvantage of the second input method is that the setting is complicated, and the complexity of the required auxiliary programs is relatively high.

In addition, although this input method can support the migration of layout rules, it requires a corresponding report of component package specification information data between different circuit boards; query each pin for setting

All of these are not conducive to work efficiency due to the complexity of the work, and at the same time, there are also doubts about the correctness brought about by human input.
