Mentor Graphics Receives IC Simulation Patent

8/8/2002 - Mentor Graphics was awarded a U.S. patent (number 6,397,172) on its adaptive model evaluation technology, a key component of its Mach TATM integrated circuit (IC) simulation design tool. The new technology benefits memory, processor and mixed-signal designers, and the patent enhances Mentor Graphics competitive advantage in providing its customers best-in-class tools at this integral aspect of the design phase.

"Adaptive Integrated Circuit Design Simulation, Transistor Modeling and Evaluation," invented by Dave Gurney, development engineer, deep submicron division, Mentor Graphics, addresses how the speed of a simulator is dependent on model evaluation techniques. Previous circuit simulators used static techniques for model evaluation, resulting in larger partitions and relatively slow simulation times. By using dynamic techniques for model evaluation, the Mach TA tool can create smaller partitions which then accelerate simulation times.

The inventions stemming from this patent enable the Mach TA tool to dynamically select how device models are evaluated, thus producing the fastest simulation results with the highest accuracy. The end user experiences faster simulation speeds without sacrificing Spice-like accuracy.
