As multi-processor system-on-chip (MPSoC) has become an effective solution to
ever-increasing design complexity of modern embedded systems, fast and accurate
HW/SW cosimulation of such system becomes more important to explore wide design
space of communication architecture. Recently we have proposed the trace-driven
virtual synchronization technique to boost the cosimulation speed while accuracy
is almost preserved, where simulation of communication architectures is
separated from simulation of the processing components. This paper proposes two
methods of simulation modeling of communication architectures in the
trace-driven virtual synchronization framework: SystemC modeling and C modeling.
SystemC modeling gives better extensibility and accuracy but lower performance
than C modeling as confirmed by experimental results. Fast reconfiguration of
communication architecture is available in both methods to enable efficient
design space exploration.
