Abstract
A method divides a layout area of an electronic part into sections, designs patterns according to circuit data of de electronic part, and draws the patterns in the layout area section by section so that the patterns in the sections may collectively form the electronic part. The method detects, among the patterns, any violation pattern that may cause a characteristic failure in the electronic part due to a section-to section connection error. Such violation pattern has a size L smaller than a threshold “k*La” where La is a section-to-section connection allowance and k is a coefficient. Also provided is an apparatus for executing the method.
