Abstract

The invention provides a power supply connection verification method and device, electronic equipment and a storage medium. The method comprises the steps of obtaining a netlist of a target integratedcircuit; analyzing the netlist to obtain device information of each device in all devices of the target integrated circuit and power supply information associated with each port of each device; detecting the corresponding device according to the device information of each device and the power supply information associated with each port to obtain a detection result; and judging whether the powersupply connection of the target integrated circuit is wrong or not according to the detection results of all the devices, and outputting wrong device information when the power supply connection of the target integrated circuit is wrong.

Description

technical field [0001] The present application relates to the technical field of integrated circuits, and in particular, relates to a power connection verification method, device, electronic equipment, and storage medium. Background technique [0002] In integrated circuit design, there will be multiple power domains. If the power supply is connected incorrectly, the chip will not work properly. [0003] The current power connection verification method is that the top-level design uses the Unified Power Format (UPF) and the port-related power in the timing characterization file to ensure the correctness of the power connection. An error may result in a wrong result of the final power connection verification, and then there is a problem of low reliability of the power connection verification. Contents of the invention [0004] The purpose of the embodiments of the present application is to provide a power connection verification method, device, electronic equipment, and st...
