Abstract: A circuit design is simulated in a simulation environment. When a simulation model in the simulation environment transfers state information to a second simulation model, the simulation environment receives the state information and makes it available to the second simulation model without simulating the transfer through the simulated circuit design.

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.

Abstract: A simulation environment includes a number of simulation domains. Particular simulation domains in a simulation environment are selectively activated and deactivated such that performance and resolution for a circuit design being simulated are dynamically controlled.

Abstract: A hardware/software co-simulation permits access to a server state from any process in the hardware/software co-simulation. In one embodiment, a co-simulation interface receives a request from a client system for configuration data for the server state in of the hardware/software co-simulation. The configuration data defines memory locations in the co-simulation from which the server state can be assembled. The interface inserts the request in the co-simulation. The co-simulation responds with the configuration information. Based on the configuration information, memory operations can be performed on the server state.
