Spectre XPS (eXtensive Partitioning Simulator) is a FastSPICE simulator that enables simulation for large, complex chip designs.

Reportedly delivers partitioning technology with up to 10x faster throughput compared to other offerings. Can measure timing while including impact of IR drop. Is built on Spectre simulation platform; allows reuse of models, stimulus, analysis and overall methodology. Spans SPICE, advanced SPICE, RF and FastSPICE; integrates into Virtuoso Analog Design Environment for mixed-signal design, and into Liberate MX memory characterization tool for SRAM memory characterization.
