Sequential simulation technique can be applied as an accurate and
inexpensive measurement approach for performance analysis of real systems.
Unfortunately, the performance of the sequential simulation degrades
when the complexity of the systems is increased. On the other hand,
parallel or distributed simulations can be applied as fast, feasible and
cost effective approaches for performance analysis of complex systems.
Synchronization is a critical issue in these simulation principles. One
of the well known synchronization methods for parallel or distribute
simulation is Time Warp which is an optimistic concurrency protocol. In
this method, different possessors process the events optimistically
without considering time stamps of the events. Then, some mechanisms are
provided to overcome the consequent out of order executions. In this talk
I introduce Time Warp protocol and its applications in digital logic
simulation which is one of the domains, that widely uses this protocol.
