Efficient Simulation of Synthesis-Oriented System Level Designs

Modeling for synthesis and modeling for simulation seem to be two competing goals in the context of C++-based modeling frameworks. One of the reasons is while most hardware systems have some inherent parallelism efficiently expressing it depends on whether the target usage is synthesis or simulation. For synthesis, designs are usually described with synthesis tools in mind and are therefore partitioned according to the targeted hardware units. For simulation, runtime efficiency is critical but our previous work has shown that a synthesis-oriented description is not necessarily the most efficient, especially if using multiprocessor simulators. Multiprocessor simulation requires preemptive multithreading but most current C++-based high level system description languages use cooperative multithreading to exploit parallelism to reduce overhead. We have seen that, for synthesis-oriented models, along with adding preemptive threading we need to transform the threading structure for good sim...
