Abstract:
A semiconductor integrated circuit reliability verification device for examining transistor-level design information on a circuit to be verified to detect any portion of the design that may cause circuit malfunction due to the effects of switching noise, comprising:partial circuit network detecting means for detecting information concerning partial circuit networks that form part of a circuit to be verified, based on information equivalent to a transistor-level net list for the circuit to be verified;maximum resistance calculating means for calculating the maximum resistance that occurs while the channel connected component, which is the driver, is operating, based on the information concerning said partial circuit network detected by said partial circuit network detecting means;gate capacitance calculating means for calculating the total gate capacitance for the portions but the inverter of a driven circuit driven by said driver, based on the information concerning said partial circuit network detected by said partial circuit network detecting means; anderror judging means for calculating the value of evaluation function, based on said value of maximum resistance calculated by said maximum resistance calculating means and said total gate capacitance calculated by said gate capacitance calculating means, and judging whether or not said calculated value is in violation of the pre-established design criteria.
