CLOCK SUPPLY CONTROL SYSTEM, DESIGNING METHOD FOR CLOCK SUPPLY CONTROL CIRCUIT AND RECORD MEDIUM RECORDED WITH DESIGN PROGRAM FOR CLOCK SUPPLY CONTROL CIRCUIT

摘要

PROBLEM TO BE SOLVED: To provide a clock supply control system capable of easily and automatically designing a gated clock, with which the characteristics of minimizing a clock skew and suppressing increase in the signal delay of an enable signal are satisfied, in a short time in gated clock design under the control of a multi- input/multi-stage enable buffer. SOLUTION: At least one two-input buffer for inputting a clock signal and the output signal of a gating circuit is inserted on the post-stage of the gating circuit directly driving an element to supply a clock and by connecting a fixed value signal to a terminal, to which the clock signal is directly connected, inside the gating circuit, to which the clock signal is directly connected, logically equivalent conversion is performed.
