Time accurate simulation
Supervisor: Jakob Engblom /UU and IAR System AB
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
