The invention provides a power network design method and device, and a storage medium. The method comprises the steps of identifying coordinates of each memory macro cell in a to-be-processed power domain; determining the coordinates of the first region, the coordinates of each second region and the coordinates of each third region according to the coordinates of each memory macro cell; determining a first metal wire arrangement parameter of the first region according to the design requirement, determining a second metal wire arrangement parameter of each second region according to the coordinate of each second region, and determining a third metal wire arrangement parameter of each third region according to the coordinate of each third region; and according to the coordinate of the firstregion, the coordinate of each second region, the coordinate of each third region, the corresponding first metal wire arrangement parameter, the corresponding second metal wire arrangement parameter and the corresponding third metal wire arrangement parameter, performing power supply network arrangement on the first region, each second region and each third region. The scheme provided by the invention can shorten the design period and ensure the power supply stability of the chip.
Description
technical field [0001] The present invention relates to the field of chip design, in particular to a power network design method, device and storage medium. Background technique [0002] In the chip design, the design of the power network is very important, which is related to the stability of the chip. The quality of the power network design directly affects the running speed of the chip and the stability of the function. If there is a weakness in the power supply in some parts of the power network, it will cause a large voltage drop in the circuit components in the problem area, which will eventually cause the circuit to function abnormally. The chip multi-power domain design means that the chip is powered by multiple power sources or internally separated from several power sources. There are complex design methods: power off (MTCMOS Power Gating), power off with state retention function (Power Gating with StateRetention), dynamic voltage and frequency adjustment (Dynami...
