Abstract:
Evaluation of electrical accessibility within a layer of a circuit to pin geometries residing within a cell boundary of the circuit is provided. The evaluating includes, for instance, checking along substantially parallel pin geometry access paths of the layer to determine possible points at which a respective pin geometry of the pin geometries within the cell boundary may be accessed. The evaluating also includes identifying which points of the possible points are accessible access points by any route of the possible routes for electrically connecting to a respective pin geometry of the pin geometries from a first side or a second side of the cell boundary, wherein at least one point of the possible points is identified as not being an accessible access point based on the at least one point being inaccessible by the possible routes.
