Charlie
Fast, accurate, automated and variation-aware library characterization for memory and mixed-signal designs
Charlie is a new generation memory and block characterization tool that produces nominal and process variation (LVF) libraries at a fraction of the runtime as existing tools that produces only nominal libraries. It achieves this by automatically applying local simulations to local variation sources, and automatically propagating the variation effects throughout the circuit.
Charlie is SPICE simulator independent and it is integrated with popular commercial SPICE and FastSPICE simulators for high performance parallel simulation.
