PROBLEM TO BE SOLVED: To provide a semiconductor integrated circuit design support system capable of automatically extracting a place where the propagation of an unfixed value of a designing circuit with a predetermined reset period given thereto occurs.;SOLUTION: The semiconductor integrated circuit design support system includes an unfixed value occurrence FF(flip-flop) detection means 1 for detecting an FF with no reset exceeding the number of clock stages as the cause of unfixed value propagation when the number of stages of FF with no reset which sequentially track connection destinations of components in a target circuit 100 and are continuously connected without going through an FF with reset exceeds the number of clock stages corresponding to the reset period.;COPYRIGHT: (C)2007,JPO&INPIT
