Abstract
There are disclosed a multi power supply integrated circuit evaluating method which is capable of detecting power supply voltage illegal connection, redundant connection, and potential redundant connection from connection descriptions contained in a multi power supply integrated circuit in the stage of circuit design and then correcting automatically such connections, and a system for embodying the same. The evaluating method comprises at least the steps of inputting a database in which various cells are registered and the connection descriptions of the multi power supply integrated circuit, detecting connections corresponding to the power supply voltage illegal connection, the redundant connection, and the potential redundant connection, registering the detected connections as the power supply voltage illegal connection, the redundant connection, and the potential redundant connection, outputting the power supply voltage illegal connection, the redundant connection, and the potential redundant connection, and correcting automatically the power supply voltage illegal connection, the redundant connection, and the potential redundant connection.
