Abstract
Disclosed are a VCD vector compression method and device based on circuit toggle behaviors. The method comprises: converting a VCD format file into a current matrix model, wherein three dimensions of the current matrix model are one time dimension and two spatial dimensions; performing preliminary screening based on an overall toggle feature: dividing the current matrix into several time segments in accordance with an equal interval in the time dimension, and performing screening according to the overall toggle feature, and forming a preliminary screened current distribution matrix by the screened time segments; performing fine screening based on region toggle features: performing further screening according to local toggle features, and forming a fine screened current distribution matrix by the screened time segments; and re-outputting the fine screened current distribution matrix as a VCD format file after vector compression.
