BIDIRECTIONAL REPEATER CIRCUIT

摘要

PROBLEM TO BE SOLVED: To provide a bidirectional repeater circuit which can be automatically inserted when automatically laying out the elements or wiring between the elements of an LSI or the like. SOLUTION: A bidirectional repeater circuit 100 is automatically inserted to a long path 1 for preventing signal delay or deterioration to occur when automatically laying out the elements or wiring between the elements of an LSI and has a first node 101 on one terminal side and a second node 102 on the other terminal side. The repeater circuit 100 is provided with a holding part 153 for holding a signal level which is outputted before a change when one node is changed from a state where both the nodes are identical to a state where one node has a different signal level and output setting parts 151 and 152 for setting the signal level of the other node from the signal level before the change to the signal level after the change while the holding part holds the signal level before the change.
