Signal selection apparatus and system, and circuit emulator and method and program

摘要

Disclosed is a system in which in order to obtain the operation parameter of a circuit based on an implementable area indicating a circuit scale that can be implemented on a circuit implementation device, circuit area information, and operation parameter measuring circuit area information, an observation signal number determining means determines observation signal information on a circuit that obtains the operation parameter of the circuit. The number of the extracted signals is determined in view of the area that can be implemented on a digital LSI or an emulator and the area of the circuit to be implemented (refer to FIG. 1).

1. A signal selection apparatus that determines information on observation signals for obtaining an operation parameter of a circuit, the apparatus comprising:
a first storage unit storing information on a circuit size implemented on a circuit implementation device; a second storage unit storing information on the circuit size; a third storage unit storing signal candidates for signals of the circuit to be observed; and an observation signal selecting unit that randomly selects an observation signal so that the circuit and a circuit that observes the selected observation signal implemented on the circuit implementation device, based on the information on a circuit size implemented on the circuit implementation device, the information on the circuit, and the signal candidates for signals of the circuit to be observed.
