Abstract: PURPOSE:To reduce clock skew between FF's by arranging wiring channels of exclusive use for clock signals, while connecting clock drivers and the FF's, just under a power supply wiring. CONSTITUTION:Wiring channels of exclusive use for clock signals 15, 16, are arranged to connect clock drivers 12, 13 and FF's 10, 11 just under a power supply wiring 17. In order to reduce clock skew between the signals 15, 16 supplied to the FF's 10 and 11, the delay times of the signals 15, 16 must be as close as possible to each other. In the above constitution, the signals 15, 16 are arranged just under the wiring 17, so that the crossing ratios to the wiring 17 are 100%. Although the signals 15, 16 intersect with other signal wirings, the crossing ratios are extremely small as compared with the crossing ratios to the wiring 17, and therefore the wiring capacitances of the signals 15, 16 are almost determined only by the relations to the wiring 17. Hence, by making the wiring lengths of the signals 15, 16 equal, the delay times of both wirings can be made coincide with each other.
