During circuit design, Design Gateway provides embedded simulation, analysis and electrical rules checking.
A complete simulation and analysis environment
CR-8000 is a complete design environment that includes fully integrated simulation and analysis tools to verify your single or multi-board designs.
During PCB layout, the Design Force embedded signal integrity, power integrity, electromagnetic interference
Electromagnetic compatibility tools provide a single environment for all of your design team’s simulation and analysis requirements
