An apparatus includes a master latch circuit including a first circuit and a second circuit, and a slave latch circuit including a third circuit and a fourth circuit. The first circuit and the second circuit may be coupled to a first shared circuit node, and the third circuit and the fourth circuit may be coupled to a second shared circuit node. The master latch circuit may be configured to store a value of an input signal in response to an assertion of a clock signal. The slave latch circuit may be configured to store an output value of the master latch circuit in response to a de-assertion of the clock signal. The master latch circuit may also be configured to de-couple the first shared circuit node from a ground reference node in response to the de-assertion of the clock signal.

Reduced power set-reset latch based flip-flop

The present invention is directed to a system and method of modeling electrical circuits. The present invention may provide improved software for predicting microchip interconnect delays, and in general for an improved semiconductor manufacturing models. Further, the invention may provide for accurate prediction of resistance, capacitance and inductance for interconnections in a semiconductor, allowing for both environmental values and process variations.
