PATTERN MATCHING METHOD, TIMING ANALYSIS METHOD AND TIMING ANALYSIS DEVICE

In the timing analysis method, connection information is compared to circuit patterns that have been stored in a memory in advance after reading the connection information of an electrical circuit, a connection information supplement process to supplement vertically circuit connection information regarding the matched circuit pattern for the stored connection information is performed when the connection information is matched with one of the registered circuit patterns, and a timing analysis of the connection information that has been supplemented by the connection information supplement process is executed.
