ABSTRACT:
Timing setting data include an arbitrary combination of a set timing signal indicating a positive edge timing and a reset timing signal indicating a negative edge timing. A sort unit sorts n pieces of the timing setting data in accordance with timing orders indicated by each of the timing setting data. With reference to the sorted timing setting data an open processor detects continuation of the set timing signals or continuation of the reset timing signals, and invalidates one of the continuous set timing signals or one of the continuous reset timing signals. An edge assigning unit sequentially assigns the set/reset timing signals remaining without being invalidated to, among the m variable delay circuits for setting/resetting, the variable delay circuits for setting/resetting in the ascending order of the frequencies of use thereof by then.
