1. A computer implemented method for devising an electronic design with disconnected field domains, comprising: identifying a plurality of metal shapes of an electronic design; reducing computational resource consumption by representing at least a portion of the electronic design with an additional model in a model for the electronic design; adding, at a patching module including or coupled with at least one micro-processor of a computing system, a plurality of patches to the model for the electronic design for multiple apertures formed by at least some of the plurality of metal shapes in the electronic design; analyzing the model to generate analysis results for the electronic design; and devising the electronic design based in part or in whole upon the analysis results.
