A system is described for managing interaction between an untimed HAL portion and a timed HDL portion of the testbench, wherein the timed portion is embodied on an emulator and the un-timed portion executes on a workstation. Repeatability of verification results may be achieved even though the HAL portion and the HDL portion run in parallel with each other. A communication interface is also described for synchronizing and passing data between multiple HDL threads on the emulator domain and simultaneously-running multiple HAL threads on the workstation domain. In addition, a remote procedural-call-based communication link, transparent to the user, is generated between the workstation and the emulator. A technique provides for repeatability for blocking and non-blocking procedure calls. FSMs and synchronization logic are automatically inferred to implement remote procedural calls. A subset of behavioral language is identified that combines the power of conventional modeling paradigms with RTL performance.
