Abstract
This report describes how an existing simulation technique for embedded systems can be extended to handle time accurate simulation. The simulation technique is based on separation of code into hardware dependent and hardware independent parts. The hardware independent part is compiled and run on a PC for simulation. The hardware dependent part is replaced with code that simulates the hardware on the PC. To perform time accurate simulation breakpoints are added to the source code. The breakpoints contain information about the execution time for the basic blocks of the code on the target system. By comparing the amount of time used on the target system between the nodes in the simulation a scheduler can synchronize their execution on the PC. The scheduler can also slow down the execution so it runs in the speed given by the times in the breakpoints. An implementation of a prototype system for Windows NT with the scheduler implemented as a DLL is described.
