Clock feeding circuit and clock wiring system |
摘要 |
Dummy power source wirings connected to a power source wiring are arranged in empty regions among the signal wirings that cross the clock wirings, the dummy power source wirings being arranged over or under the clock wirings in a manner to cross the clock wirings. The dummy power source wirings are formed to equalize the capacitances of the wirings whose lengths should be equalized among, for example, the clock distributing circuits or among the clock drivers.
