PROBLEM TO BE SOLVED: To provide a semiconductor integrated circuit design device which achieves automatic insertion and optimization of a synchronization circuit. SOLUTION: The semiconductor integrated circuit design device includes: an interface circuit information extraction part 111 for specifying a transmission register and a reception register configuring an interface to be synchronized, from the circuit description data of a semiconductor integrated circuit, clock domain information and non-synchronization place information; an insertion place candidate specification part 112 for specifying the number of supply sources as the number of transmission registers as data supply sources for each of the reception registers, and for specifying the insertion place candidates of the synchronization circuit based on the number of supply sources; an insertion place specification part 113 for specifying the number of output destinations as the number of reception registers as data output destinations for each of the transmission registers, and for specifying the insertion place of the synchronization circuit based on the number of output destinations and the insertion place candidate information; and a synchronization circuit insertion part 114 for preparing circuit description data of the semiconductor integrated circuit where the synchronization circuit has been inserted into the insertion place.
