Abstract
According to one embodiment, a circuit noise determination system includes a reading unit that reads a netlist representing a target circuit and analysis settings for noise analysis. A noise calculation unit is provided in the system to calculate noise values of circuit elements of in the target circuit according to the netlist along with a circuit classification unit that identifies and classifies circuit element in the target circuit. The system further includes a noise determination unit that outputs a notification regarding elements exceeding a noise upper limit reference value set based on a plurality of noise determinations prepared in advance for each circuit classification.
