Nassda obtains patent for its circuit simulator

Nassda Corp., a provider of full-chip circuit verification software, announced that they have been granted US patent no. 6,577,992, entitled "Transistor Level Circuit Simulator Using Hierarchical Data." This is the first patent issued to Nassda and relates to the validation of the functionality and performance of microelectronic circuits prior to fabrication.

The invention describes how the hierarchical nature of microelectronic circuits may be used to simulate the electrical behavior of very large circuits while minimizing the simulation time and memory required. Consequently, circuit designers can perform full-chip circuit simulations in a reduced amount of time.
