Abstract
With respect to layout data of a semiconductor integrated circuit, a latch-up verifying operation is carried out in high precision. In a latch-up verifying method, a well region, a transistor region, and a substrate contact region are extracted from layout data of a semiconductor integrated circuit formed on a semiconductor substrate; and steps for separately setting over-sizing values are sequentially executed based upon the respective extracted information.
