ANSYS® Path FX™ is a critical path analysis tool that complements existing static timing analysis sign-off tools. It can evaluate hundreds of thousands of timing paths and clock trees in an SoC for delay and variance for even the largest designs. Path FX has production-proven, SPICE-like accuracy to tackle the most advanced manufacturing processes, and the functionality to account for all critical contributors to delay and constraints across multiple process, voltage, temperature corners and scenarios. Path FX makes it practical to calculate timing with variation on a full SoC without taking any shortcuts. With a fully threaded and distributed architecture and the ability to run on thousands of CPUs, turnaround time scales inversely with the number of CPUs available.
