    • In a method and apparatus for designing semiconductor integrated circuit, a path delay information producing section produces path delay information by performing a static timing analysis based on delay information of a cell and subject circuit information. A correction table producing section calculates circuit-dependent delay variation for each combination of circuit parameter values based on variation information of an element, and stores the calculated circuit-dependent delay variation in a delay correction table. A statistical path delay producing section calculates the circuit parameters for a path based on the subject circuit information and the path delay information, obtains the corresponding circuit-dependent delay variation based on the circuit-dependent delay variation correction table, and calculates and outputs statistical path delay information based on the circuit-dependent delay variation and the corresponding path delay information. Thus, it is possible to obtain a value close to an actual path delay worst value with only a little addition of calculation time.

    • In a flip-flop circuit which includes an input section using a dynamic circuit and an output section using a static circuit and which captures data during a period of a pulse width shorter than a clock cycle, the number of transistors, circuit area and power consumption are reduced. In FIG. 1, an output signal of an inverter circuit INV1 constituting a latch circuit 2 connected to the output terminal of an input section 1 is used as an input signal of a control section 3. Thus, a control signal output from the control section 3 to the input section 1 is stabilized, thereby suppressing unnecessary operation of circuit elements and reducing unnecessary power consumption. In addition, the configuration of the control section 3 is simplified. As a result, the number of transistors constituting the circuit and the circuit area can be reduced.
