Filed: 1992-07-06
Abstract: PURPOSE:To check a critical pass by discriminating the calculated result of set-up time/hold time for the clock of a cell inside a circuit operated in synchronism with the clock within an allowable value. CONSTITUTION:First, the result of a logic simulation is read in the form of text data. Successively, the list of the cells synchronized with the clock inside the circuit is prepared and the position inside the circuit of the cell selected from the list is searched. Then, the set-up time and the hold time of the selected cell are calculated based on the data of the logic simulation, the intrinsic name of the selected cell and the calculated result are displayed, the processings are repeated and all the cells in the list are checked when the calculated result does not satisfy the allowable value. When the calculated result satisfies the allowable value, a normal operation for the clock is discriminated.
