DESIGN PROGRAM FOR SEMICONDUCTOR INTEGRATED CIRCUIT DEVICE, DESIGN SUPPORT SYSTEM FOR THE SAME, DESIGN METHOD FOR THE SAME, SEMICONDUCTOR INTEGRATED CIRCUIT DEVICE, AND ELECTRONIC APPARATUS
PROBLEM TO BE SOLVED: To provide a design support program, etc., for a semiconductor integrated circuit device for suppressing increase of a chip size or working man-hour by detecting and correcting only a real transition time error in accordance with the operation frequency of each cell.;SOLUTION: The design support program makes a computer function as a transition time calculating means 12, a transition time standard value setting means 14, and a transition time error detecting means 16. The transition time calculating means 12 calculates the transition time of an input signal of each cell, on the basis of a net list including connection information of the plurality of cells. The transition time standard value setting means 14 sets the standard value of the transition time of the input signal in each cell, on the basis of correspondence relation which is previously defined about the operation frequency and the standard value of the transition time. The transition time error detecting means 16 detects the error of the transition time by each cell, on the basis of the transition time calculated by the transition time calculating means 12 and the standard value set by the transition time standard value setting means 14.;COPYRIGHT: (C)2009,JPO&INPIT
