Hierarchical Full-chip Circuit Simulation and Analysis The need for high-capacity, high-performance transistor-level verification has increased as nanometer silicon effects now dominate design performance. Today’s designs require precise control of leakage effects to meet power budgets, at the same time that reduced supply voltages and increased interconnect parasitics leave little design margin for meeting performance specifications. HSIM is uniquely architected to meet the challenges of circuit verification at 65nm, 45nm and below through its innovative hierarchical simulation engine - delivering the capacity you need for precise analysis of post-layout effects. Analog, mixed-signal, memory and SoC designs benefit from the ability to perform more extensive transistor-level analysis while overcoming the inefficiencies of flat SPICE simulators. HSIM increases confidence in results before tapeout, to deliver predictable success.
