Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To automatically implement minimum delay assurance of a flip-flop by adding minimum delay constraint so as to satisfy the hold time of a flip-flop on the next stage, performing logical combination through maximum delay constraint and minimum delay constraint and outputting a net list. SOLUTION: A delay measuring part measures delay time between a start point flip-flop (expressed as F/F below) and an end point F/F (S14) and decides whether or not the hold time of the end point F/F is longer than the delay time between the start point F/F and the end point F/F (S15). Since minimum delay constraint is not satisfied if the delay time is shorter than the hold time, go to a step S9. Since the minimum delay constraint is satisfied if it is larger, go to a step S12. An F/F to be selected runs short (S12), a logical combination part performs logical resynthesis through maximum delay constraint and the minimum delay constraint (S16). A net list outputting part outputs a net list that is a synthetic result (S17).
