Patent ID: 7149676

Claim:
A method of simulating a system, the method comprising: modeling the system to be simulated using computer code to produce a system model comprising at least a first portion and a second portion; in a simulator, performing simulation in a functional simulation mode having a first accuracy level for at least a first portion of code comprising the first portion of the system model, the behavior of the system represented by the first portion of code being simulated in the functional simulation mode without regard to execution time to thereby obtain information about functionality of the first portion of the simulated system; and in the same simulator, performing simulation in a performance simulation mode having a second accuracy level different from the first accuracy level for at least a second portion of code comprising the second portion of the system model, the behavior of system represented by the second portion of code being simulated in the performance simulation mode with regard to execution time to thereby obtain information about the performance of the second portion of the simulated system.
