摘要:
A method and apparatus for combining emulation and simulation of a logic design. The method and apparatus can be used with a logic design that includes gate-level descriptions, behavioral representations, structural representations, or a combination thereof. The emulation and simulation portions are combined in a manner that minimizes the time for transferring data between the two portions. Simulation is performed by one or more microprocessors while emulation is performed in reconfigurable hardware such as field programmable gate arrays. When multiple microprocessors are employed, independent portions of the logic design are selected to be executed on the multiple synchronized microprocessors. Reconfigurable hardware also performs event detecting and scheduling operations to aid the simulation, and to reduce processing time.
