ABSTRACT:
Disclosed is a method, system, and computer program product for routing, modeling routes, and measuring congestion. In some embodiments, Gcells are implemented with reduced number of nodes to facilitate route modeling and congestion measurement. Some embodiments are particularly suitable for direct congestion and routing analysis of diagonal routing paths. In this way, congestion analysis can be directly performed along diagonal boundaries for diagonal routes, without requiring association with Gcell boundaries on Manhattan routing layers.
