Embedded systems - multiprocessor systems on a chip with application specific instruction-set processors (ASIPs) - become indivisible part of our everyday lives. They are everywhere. Therefore, powerful and flexible way of design and simulation of these systems is needed. The simulators of ASIPs are created using an architecture description language called ISAC. In this paper, the basic concept of simulation, the communication protocol among ASIPs and the three-state synchronization protocol that is used in the distributed multiprocessor simulation are described. Further, the basic concept of profiling and consequential evaluation of profiling information is described. One needs the results from the simulation itself and the results from the profiling to find bugs in the system and to optimize the system as a whole.
