Abstract
Disclosed are methods, systems, and articles of manufactures for implementing correct-by-construction physical designs with multiple-patterning-awareness by identifying a first set of grids for a layer based at least in part upon characteristics of other layer(s), identifying a set of tracks for the layer to implement the physical design for the layer, and implementing a shape in the physical design by at least terminating an end of the shape at a grid of the identified first set of grids. The end of the shape may be extended or contracted from its as-design location to the grid. The physical design thus implemented is correct-by-construction and is free of violations of one or more directional design rules.
