High-performance Library Characterization for Standard Cell Libraries, Memories, and IPs

Empyrean Liberal™ provides an efficient and accurate solution for timing and power characterization. The built-in Empyrean ALPS SPICE engine, combined with advanced multi-threading and multi-processing technologies, delivers high performance and scalability. Comprehensive validation and dynamic debugging capabilities further enable analysis and verification down to the SPICE simulation level.

Empyrean Liberal-Mem™ and Empyrean Liberal-IP™ are next-generation characterization solutions for memories and mixed-signal blocks, respectively.  They generate nominal and process variation (LVF) libraries in a fraction of the runtime required by conventional tools, which typically generate only nominal libraries. This efficiency is achieved through the automatic application of local simulations to variation sources and the automatic propagation of their effects throughout the circuit.
