Design and realization of a system simulator

System simulations seek to strike a balance between accuracy and performance. This paper elaborates on the realization of a system simulator. The SystemC-based platform provides the simulation environment for the target application and the cycle-accurate performance evaluation for the optimization methodology. Compared with the result of the actual prototyping simulation, the maximal evaluation error of the simulator is less than 0.02% and the simulating speed is 800 times faster than actual prototyping simulation.
