Abstract
As MPSoC has become an effective solution to everincreasing
design complexity of modern embedded systems, fast
and accurate cosimulation of such systems is becoming a tough
challenge. Cosimulation performance is in inverse proportion to
the number of processor simulators in conventional cosimulation
frameworks with lock-step synchronization schemes. To overcome
this problem, we propose a novel time synchronization technique
called trace-driven virtual synchronization. Having separate
phases of event generation and event alignment in the cosimulation,
time synchronization overhead is reduced to almost zero,
boosting cosimulation speed while accuracy is almost preserved. In
addition, this technique enables (1) a fast mixed level cosimulation
where different abstraction level simulators are easily integrated
communicating with traces and (2) a distributed parallel cosimulation
where each simulator can run at its full speed without
synchronizing with other simulator too frequently. We compared
the performance and the accuracy with MaxSim, a well-known
commercial SystemC simulation framework, and the proposed
framework showed 11 times faster performance for H.263 decoder
example, while the error was below 5%.
