Problems solved by technology

Therefore, hardware engineers need to spend a lot of time checking the corresponding relationship between each board connector and the backplane connector signal definition on the basis of completing the single board principle design, which is time-consuming, laborious and error-prone
[0005] In addition, during the PCB layout process, the PCB engineer will require the hardware engineer to adjust the signal definition in view of the placement of the device and the difficulty of routing, etc., which will cause a series of signal adjustments. The signal definition adjustment affecting the connector is very common. For For some projects with a tight development cycle, the time overhead of this part is sometimes fatal to the time compression of the product design cycle

Abstract

The invention discloses a connector signal definition proofreading method and system based on modular design, and belongs to the field of electronic design automation, and aims to solve the technicalproblem of how to realize efficient correction of connector signal definition between modules and ensure the correctness of product design, and the technical scheme is as follows: the method comprisesthe following steps: S1, establishing a database covering various connectors; S2, according to the connection relationship between the male head and the female head, constructing a model corresponding relationship between the connectors; S3, according to related specifications of the connector, establishing a corresponding relationship of pins between the connector male head and the connector female head; S4, loading board card principle design files corresponding to the two modules of the modular product with the interconnection relationship; S5, filling in proofreading parameters between two modules of the modular product, namely connector bit numbers of every two modules which are connected with each other; S6, according to the proofreading principles established in the step S2 and thestep S3, sequentially and circularly checking whether the proofreading parameters listed in the step S5 are correct or not.

Description

Technical field [0001] The invention relates to the field of electronic design automation, in particular to a connector signal definition proofreading method and system based on modular design. Background technique [0002] "Standardization, modularization, and serialization" is the mainstream direction of the development of electronic products today. There are several common modular design standards in the world: CPCI standard, VPX standard, ASAAC standard, etc., and the CPEX standard used by the navy is derived in China. Different standards correspond to different connectors: CPCI standard corresponds to CPCI connector, VPX standard corresponds to VPX connector, ASAAC standard corresponds to VPX connector, and CPEX standard corresponds to CPCI connector. Modular product design is implemented based on connectors in compliance with various standards. Connector signal definitions undertake the up-coming and issuing of signals. Its correctness becomes the key to the success or fail...
