Methods, systems, and articles of manufacture for tessellating and labeling routing space for routing electronic designs

Abstract

Various aspects described herein create tessellated regions by identifying tessellation lines in one or more directions based at least on fixed shape(s) or route(s). New cells or shapes are added to the design by aligning at least some of the boundary segments of the new cells or shapes with existing tessellation lines. Tessellation lines are dynamically adjustable. At least some tessellated regions are associated with initial or tentative track pattern labels some of which are iteratively updated during implementation of the design. Multiple candidate track patterns may be ranked based on consistency costs to determine a tentative track pattern. Designs may be implemented with a trackless approach in trackless region(s) followed by a tracked approach based at least in part upon the initial or tentative labels that are dynamically adjusted during implementation. Capacities and demands are assessed at boundary segments of cells by using the tracked or trackless approach.
