Method, module and system for data communication in integrated circuit simulation, storage medium

Abstract

The invention discloses a method, a module and a system for data communication in integrated circuit simulation, and a storage medium. The method comprises the steps of: transmitting data to a next simulation operation module B when the data is updated in a simulation operation module A in each clock period, dividing all the data into a plurality of fixed-length data sets in sequence, and performing position calibration and sorting on the data sets in sequence to form calibration parameters; if the data in one data set is updated, calibrating the data set as an updated data set; and then, forming a data packet by the calibration parameters and the data set calibrated to have the update, and transmitting the data packet to a simulation operation module B. According to the method, data updating does not exist in each clock period S, the reason why all the data are updated at the same time is avoided, the data size is compressed by reducing duplicated data sending, and therefore the transmission efficiency is improved, and the bottleneck problem of the transmission efficiency is solved.
