Embodiment Construction

[0011] Those skilled in the art can realize the present invention with reference to the following embodiments. Of course, the following embodiments can also be implemented in the form of a computer program, and a computer-readable storage medium is used to store the computer program, so that the computer can execute the derating inspection method.

[0012] figure 1 It is a flowchart illustrating a derating checking method according to an embodiment of the present invention. First open the circuit layout design file (step S110), and then from the multiple material numbers (partsname or Parts number) used in the circuit layout design file, filter out one or more target materials belonging to the target category (such as capacitors). number (step S120). Here keywords can be used to retrieve all object numbers belonging to a certain object category. For example, assuming that the part numbers starting with "6010" are all capacitors, you can use the keyword "6010" to retrieve al...

Abstract

The invention discloses a derating inspection method, which comprises opening a circuit layout design gear, screening at least one target part number belonging to the target class from a plurality of part numbers (parts number) used in the circuit layout design gear, obtaining the rated voltage value according to the target part number, obtaining the element number of at least one element using the target part number in the circuit layout design gear according to the target part number, obtaining a first connection name (net name) and a second connection name respectively connected with the two ends of the element according to the element name, and judging whether the derating voltage of the element fits for the rated voltage value according to the first connection name and the second connection name.

Description

technical field [0001] The present invention relates to an inspection after circuit layout, and in particular to a method for inspecting derating of parts in circuit layout. Background technique [0002] After completing the circuit layout, various checks are usually performed. Derating inspection is one of many inspection items. Traditionally, when performing derating checks on parts (such as capacitors) in circuit layouts, inspectors have to manually search the entire circuit diagram, part by part, according to the position numbers of the parts. After searching the name of a certain part, it is judged manually whether the derating has passed or exceeded the normal rated voltage of the capacitor according to the signal potential connected to the two terminals of the capacitor. However, the number of capacitor components used in the circuit layout of general products ranges from dozens to thousands. Manually checking the derating one by one is quite time-consuming and aff...
