Dynamic width-space patterns for handling complex DRC rules

Abstract:

Embodiments according to the present disclosure relate to physically implementing an integrated circuit design using track patterns while conforming to the requirements of complex color based track systems, and using information about instances that have been included in the design. According to some aspects, the present embodiments provide "Dynamic Width Space Patterns (DWSP)" which are WSPs that are modified dynamically in consideration of neighboring geometries such that shapes created or edited using WSPs are design rule compliant. Embodiments can include providing visual indicators in a display of a portion of a design that is being created or edited, as well as possibly other alerts, so as assist a designer in creating a design rule compliant integrated circuit design that is also subject to WSPs.
