Abstract
A computer is programmed to use at least one rule to identify from within a layout of an IC design, a set of regions likely to fail if fabricated unchanged. An example of such a rule of detection is to check for presence of two neighbors neither of which fully overlaps a short wire or an end of a long wire. The computer uses at least another rule to change at least one region in the set of regions, to obtain a second layout which is less likely to fail in the identified regions. An example of such a rule of correction is to elongate at least one of the two neighbors. The computer may perform optical rule checking (ORC) in any order relative to application of the rules, e.g. ORC can be performed between detection rules and correction rules i.e. performed individually on each identified region prior to correction.
