Screening method and system for accessory

Abstract

This invention relates to a parts filter system and its method, wherein, the system comprises database, set module and filter module and the method comprises the following steps: firstly collection each circuit to form parts height information and storing the information data into database; then setting the design circuit needed height; finally, according to the set result, selecting all set part data from database for execution circuit design operation.

Description

technical field [0001] The present invention relates to a wiring technology, in particular to a system and method for screening circuit components. Background technique [0002] The general wiring operation can be divided into two stages. The first is the circuit design stage. In this stage, the electronic design engineer uses the circuit design software (such as ConceptHDL) to manually complete the attribute setting of each circuit one by one. After completion, the corresponding output file is generated by the design circuit software, and then the output file is read through the circuit routing software (such as Allegro) and enters the circuit routing stage. In this stage, the electronic design engineer must perform rule setting operations for each circuit , to generate the final line map data. [0003] Although the existing wiring technology uses professional computer software to assist in completing relevant circuit design operations, there are still many shortcomings. ...

[0004] However, in the various parts retrieval methods provided by the existing methods, there is no function of using the height of the parts as a retrieval condition. Therefore, due to the negligence of the circuit designer, the parts exceeding the height are often placed in the height limit area. Putting parts exceeding the height into the height limit area, for example, when placing parts with a height of 20 microns into the height limit area with a height range of less than 15 microns, the entire circuit board will be scrapped

Therefore, the existing parts selection import method often causes unnecessary economic losses to the enterprise due to work negligence, and there are usually hundreds or thousands of electronic components placed on a circuit board, if the existing parts selection import method is used to import parts, it will inevitably Increase the time for placing parts, resulting in low work efficiency, it is difficult to effectively save time, and it is not in line with economic benefits
