Research Of The Isomerous EDA Design Data Checkup Technology In Digitalization Test Systems

In order to find the design flaws in advance, enhance the design quality and avoid the test work unnecessary, the product designs should be checked up automatically before the products being tested. So it is greet necessary to set up an isomerous EDA design data checkup subsystem in the digitalization test system.Under the engineering background, the formats of the schematic and PCB documents of Protel, Cadence and Mentor are analyzed. The standard public document formats of the schematic and PCB based on the test requirements are constituted. The corresponding data transformation interface is developed. The related check rules which are sorted into the schematic checkup rules, the PCB checkup rules and the schematic and PCB association checkup rules are set down on the basis of engineering experience. Based on these rules a checkup rules database is built. And the checkup flows to check the design data on the corresponding public documents transformed are given.The isomerous EDA design data checkup system has the advantages of simple structure, easy operation, good expansibility and strong practicality. And it has a great practical value and application prosperity. The design idea of the checkup system mentioned can also be used in other isomerous EDA domains such as design, manufacture and quality control.
