Abstract
A latch conversion circuit which is to be added to a basic logic circuit to obtain a latch circuit having an extremely small through delay amount is prepared in advance. Moreover, provided is means for obtaining a latch circuit position whereat the shifting of the clock edge, such as skew or jitter, can be absorbed to the maximum extent possible, and for forming a latch circuit by adding the latch conversion circuit to the basic logic circuit located at the obtained point. Accordingly, a latch circuit which is not, to the extent possible, affected by skew or jitter can be designed.
