After doing transient analysis and select the entry-points, it is time for the characterization step to run HspiceAUTO.pl. Before running the script, we should add some information into the scripts. In HspiceAUTO.pl, we need to enter the name of the cells we want to characterize and the period of the input pin signal. It is shown as below:
HspiceAUTO.pl will call Spectre2Hspice.pl, run Hspice simulation and then HspiceAUTO.pl will call fallrisetable.pl.
