Analysis on HSpice performance trade-off versus simulation time

This study aims to create a performance analysis on HSPICE with respect to accuracy and simulation time through the use of HSPICE options. Specifically, the suitability of the use of HSPICE as a single simulation platform for both functional and performance simulation coverage have been evaluated. Three test circuits have been categorically selected, namely combinational logic, sequential logic and analog for the performance of this tool. Accordingly, HSPICE options were pre-determined by using HSPICE User Guide: Simulation and Analysis and tested with respect to the first three process corners (TT, SS and FF). Significant findings were concluded that by changing the options in HSPICE, the accuracy can still be maintained even if the simulation time was reduced.
