Abstract
Methods and systems for implementing repetitive track patterns for electronic designs are disclosed. The method determines a track pattern within a period and repeats the track pattern for a number of times to form repetitive track patterns. Compliance with photomask designation design rules and track pattern design rules by both the track pattern and the repetitive track patterns is maintained by adding one or more intermediate tracks. A track may be added or removed from the track pattern or replaced by another track associated with a different width by using one or more intermediate tracks. The method may validate a period and replace an invalid period with a valid period. During the identification of the tracks in a track pattern for constructing repetitive track patterns, the method also forward predicts a predetermined number of tracks or predicts one or more tracks for a predetermined distance.
