Subject: Optimistic Parallelisation of SystemC
Abstract:

Systems-on-chip (SoCs) are becoming more complex and more widespread. Virtual prototyping tools are critical to the rapid development of embedded software. SystemC is the industry standard for simulation of SoCs today; however, its performance is becoming an issue. We describe an experiment in parallelising SystemC for SMP machines by running multiple schedulers each responsible for a subset of the available SystemC processes. Each scheduler has its own local time and does not synchronise automatically with the others. We provide an interface for specifying coarse-grain and fine-grain timing constraints to enable the program- mer to write correct models in an intuitive way. Our work identifies the problems that occur when using fine-grain timing constraints and evaluates some solutions. We show that it is possible to obtain good speed-up even for relatively complex models.
