A method of verifying a design rule check script,

Abstract

The invention discloses a method for verifying a design rule check script, which comprises the following steps: S1, extracting a plurality of graphics units of different classes from a graphics unit library according to graphics classification rules 2, mapping graphics unit of that same kind on the same layout to form test layout of a plurality of graphics units respectively associate with each class; S3, sequentially verifying and testing the design rule check script on each test layout and generating a test result; S4, judging whether the test result conforms to the feature relation rule corresponding to the graphics unit of the corresponding category; If not, turning to S6; S5, judging that the design rule check script passes the verification test, and publishing the design rule check script; S6, modifying the design rule check script, and then turning to S3. The technical proposal has the beneficial effects that the test layout contains all graphical structures defined in the design rules, and the design rule check script test based on the test layout has comprehensiveness and accuracy.

Description

technical field [0001] The invention relates to the technical field of design for manufacturability, in particular to a method for verifying a design rule check script. Background technique [0002] PCB (Printed Circuit Board), the Chinese name is printed circuit board, also known as printed circuit board, is an important electronic component, a support for electronic components, and a carrier for electrical connections of electronic components. In PCB design, design rules are the key to the success or failure of a PCB design. Due to the physical characteristics of the device and the limitations of the process, the size of the physical layer on the chip and the design of the layout must comply with specific rules. These design rules are formulated by each integrated circuit manufacturer according to its own process characteristics and technical level. Therefore, different processes correspond to different design rules. Designers of integrated circuits usually design the l...
