Title:
LAYOUT LIBRARY OF FLIP-FLOP CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2012/070821
Kind Code:
A3
Abstract:
Provided is a layout library having a plurality of unit layouts in which the same flip-flop circuit is implemented. In the layout library, at least two unit layouts have mutually different arrangement structures. Therefore, coupling capacitances seen at an equal node with respect to the two flip-flop circuits appear to be different from each other. A semiconductor designer can select a layout in which a desired coupling capacitance is set through wiring, and through this, can adopt a required flip-flop circuit.
