Abstract:
Signal selecting apparatus 100 according to the present invention for determining an operation parameter of circuit 101 includes circuit analyzing means 110 for enumerating signals in the circuit that are to be measured for the operation parameter when information of the circuit is input thereto, observation signal number determination means 111 for statistically determining the number of observation signals required to determine the operation parameter from the width and reliability of an estimated error and from the number of enumerated signals, and observation signal selecting means 112 for selecting, from the enumerated signals, the same number of signals as the number of observation signals.
