PROBLEM TO BE SOLVED: To provide a source code debugger capable of displaying information on a pipeline of a cycle accurate ISS under execution of simulation of a software, and grasping accurately the execution state of each instruction in pipeline processing. SOLUTION: This source code debugger 1 is equipped with a CPU 5, a display device 13, an input device 17, a data storage device 18 and a program storage device 19. The CPU 5 is equipped with a resource information acquiring means 11, a resource information display means 12, an ISS control means 14, a pipeline information display means 15 and a pipeline information acquiring means 16. The pipeline information acquiring means 16 acquires address information under execution at each stage of the pipeline processing, information of a register under processing or the like from the cycle accurate ISS 10. The pipeline information display means 15 executes processing for displaying the information acquired by the pipeline information acquiring means 16 on the display device 13.
