Mixed Verification Apparatus for Mixed Emulation/Simulation and Mixed Verification Method Using the Same

PURPOSE: A verification system and method mixing the simulation and the emulation of the digital circuit is provided to prototype a designed digital circuit with a plurality of programmable chips, to emulate the prototype of the digital circuit, and to automatically convert the emulation process into a software based simulation in the middle of the emulation or vice versa. CONSTITUTION: A verification system and method comprises a mixed checkup system software(32), a relay module(36), and a relay cable(26). The system software(32) generates HDL(Hardware Description Language) codes describing tasks of an additional circuit for an I/O pin probing a checkup digital circuit implemented over an RFPD(Reusable Field Programmable Device)(12) installed on a prototyping board. The system software also generates a programming pattern on the RFPD, and performs the probing action by using the HDL codes. The state information is automatically transferred to a simulator(34) during an execution of the checkup digital circuit implemented on the RFPD(12).
