ABSTRACT:
The present invention pertains to the field of electronic design automation (EDA). More particularly, this invention relates to using coherent state among multiple simulation models within an EDA simulation environment. Two related inventions are described. One invention selectively activates certain simulation domains in an electronic design automation (EDA) simulation environment at various times during the simulation of a circuit design and maintains timing synchronization among the various domains. The other invention makes state information accessible to simulation models in an EDA simulation environment without the necessity of simulating data transfers in the simulated circuit design. In various embodiments, the inventions increase efficiency and versatility of a simulation environment.
