Description

technical field [0001] The invention relates to microprocessor design verification, in particular to an FPGA (Field Programmable Gates Array, FPGA for short) physical prototype verification device in the simulation verification of general microprocessor design. Background technique [0002] At present, in the functional verification of general-purpose microprocessor design, dynamic simulation is still the dominant verification method. Dynamic simulation verification mainly includes software HDL (Hardware Description Language, HDL for short) simulation and hardware FPGA physical prototype simulation. The advantages of using software HDL simulation method: first, the flexibility of using software simulation is high, and simulation verification can be carried out at various levels of design module level, microarchitecture level and system level; second, the use of software simulation The method can provide a very good debugging environment. Usually, a graphical interface can b...
