Title:
HARDWARE SIMULATION CONTROLLER, SYSTEM AND METHOD FOR FUNCTIONAL VERIFICATION
Document Type and Number:
WIPO Patent Application WO/2014/146073
Kind Code:
A3
Abstract:
Systems and methods of using hardware to simulate software, specifically the semantic operations defined in HDL simulation languages. Traditional software HDL simulation kernel operations of advancing time, activating threads in response to notified events, and scheduling those threads of execution are handled via a simulation controller. The simulation controller is comprised of a timing wheel, an event-processor, a thread/process dispatch engine, a token processor, and a resource-allocator. These components work together with a control logic component to perform the semantic operations of an HDL software kernel.
