Test device generating stimulus based on software, method for testing using the same and computer-readable storage medium storged program for generating the stimulus

PURPOSE: A verification method simulating a verification unit designed by an HDL is provided to improve a test coverage about a verification unit by preparing a test code in a software type or a software based on open source. CONSTITUTION: A task is described by an HDL(Hardware Description Language) of a hardware level(S411, S412). A test code is generated in reference to code(S417). The test code is described by an SDL(Software Description Language). The test cord is generated as a stimulus file. The stimulus file is described by the hardware level language. A characteristic of the circuit is verified through the stimulus file(S420).
