IPC: H01L27/04
Filed: 1996-10-25
Abstract: PROBLEM TO BE SOLVED: To obtain a circuit simulation apparatus capable of predicting the occurrence of the latch up and location thereof. SOLUTION: A layout parameter extractor 100 extracts possible latch up elements which may cause the latch up from a layout drawing to create circuit connection information including circuit-like connection information of the latch up elements. A simulator 200 simulates a semiconductor integrated circuit including the latch up elements as circuit elements to output simulation result D3.
