Abstract
A logic circuit for board power-supply evaluation to be incorporated into a logic device loaded on a product board includes a circuit that simulates an operation of the logic device so that utilization rate is variable at an arbitrary frequency by use of a predetermined circuit in all available logic elements of the logic device; a circuit that judges normality/abnormality of an operation of the operation simulation circuit; a utilization control circuit that varies and controls utilization rate of the logic device by controlling execution of an operation of the operation simulation circuit based on a judgement result of the operation judgement circuit and sets a utilization rate when the operation simulation circuit is instructed to stop the operation; and a utilization output circuit that outputs the judgement result of the operation judgement circuit and the utilization rate set by the utilization control circuit to the outside.
