Abstract

A DRC tool optimized for analyzing early-stage ('dirty') IC layout designs by performing one or more of (a) automatically selectively focusing DRC processing to selected regions (i.e., layers and/or cells) of a dirty IC layout design that are most likely to provide useful error information to a user, (b) automatically selectively ordering and/or limiting rule checks performed during DRC processing to provide the user with a manageable amount of error data in a predetermined reasonable amount of time, and (c) automatically providing error data in a graphical manner using a contrasting dot to indicate the location of each rule violation, whereby relevant problem areas of the dirty IC layout design are easily identified for correction by a human user, and non-relevant areas (e.g., missing block regions) can be efficiently identified and ignored, thereby facilitating efficient modification of the IC layout design.
