[PROBLEMS] An emulation, simulation, and test structure that has excellent observability, testability, and controllability and can shorten development time without using an expensive tester for testing and debugging large-scale integrated circuits. And provide a way. The emulation device (11) distributes common control information (8801) to each of a plurality of clock domains (1213, 1215, 1217) to which the emulation device is divided, and separate clocks to the clock domains. Give control (8905, 8907, 8913). [Selection] Figure 88 |
