PCB design method and system automatically leading in design rule

Abstract

The invention discloses a PCB design method and a system automatically leading in a design rule. The method comprises the following steps: S1. determining a design rule needed by PCB design and storing; S2. leading the stored design rule into a PCB design tool; S3. using the PCB design tool and the led-in design rule to perform necessary PCB design. The invention causes the design rule in the PCBdesign process to be conveniently led in and ensures the accuracy of the led-in design rule, so that PCB design is more standard, and the PCB design performance is ensured. Meanwhile, the invention also reduces the workload of CAD engineers, QA engineers and production technologists and is convenient to upgrade and maintain each PCB design rule.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a PCB (PCB Printed Circuit, printed circuit board) design method and system for automatically importing design rules. Background technique [0002] During the PCB design process, it is usually necessary to follow the corresponding design rules, such as the allowable spacing between device connections, the allowable width of the connection lines, etc. The design rules are usually recorded in the enterprise specifications, and the PCB design process is based on Enterprise norms are carried out. At present, the process of introducing the design rules adopted is as follows: figure 1 As shown, it includes: the production technologist formulates the enterprise specification for PCB design according to the feedback information in the PCB production process, and the PCB designer, that is, the CAD (computer-aided design) engineer introduces the design rules according to the enterprise ...

AI Technical Summary

Problems solved by technology

Therefore, the process of inputting design rules not only takes a lot of time, but also needs to comprehensively consider the enterprise specifications and the information conveyed by the production technologist, making it difficult to guarantee the accuracy of the data, and of course the data corresponding to the imported design rules cannot be guaranteed is the current optimal value

[0006] At the same time, for the PCB design rules input by CAD engineers, QA (Quality Assurance) engineers need to spend a lot of time checking the CAD engineer's design item by item, which further reduces the efficiency of PCB design.
