Patent ID: 7594207

Claim:
A computer-implemented method, comprising: identifying, by a computer, an instance of a particular element-point pair, wherein the particular element-point pair indicates an association between an interconnect element of a first type of interconnect element and a point located at a particular spatial location relative to the interconnect element, and wherein the instance of the particular element-point pair is a particular occurrence of the particular element-point pair involving a first interconnect element of the first type of interconnect element and a first location in a circuit assembly design; accessing previously computed marking information corresponding to the particular element-point pair, wherein the previously computed marking information comprises information indicating one or more types of interconnect elements that can be positioned at the particular spatial location without violating a set of one or more design rules applicable to the first type of interconnect element; and associating in machine memory the previously computed marking information with the instance of the particular element-point pair such that the previously computed marking information is associated with the first location in the circuit assembly design without having to recompute the previously computed marking information.
