The Totem platform from Apache Design Solutions provides a comprehensive co-simulation framework for analog, mixed-signal, and custom circuit designers. It analyzes static (IR, EM) and dynamic noise (DvD1) for the power and ground network at the IPor full-chip level, and the impact of current flow on signal lines (signal EM). It also provides a comprehensive full-chip solution for modeling and simulating noise injection, propagation, and coupling through the on-die power grid RLC, substrate RC, and package RLC networks. Totem operates at the transistor level using standard industry format data as input and provides results in an easy-to-use, unified environment.
