1. A computer implemented method for implementing electronic designs using constraint driven techniques, comprising: using a computing system having at least one processor or at least one processor core to perform a process, the process comprising: identifying, with a physical implementation rule module including or functioning in conjunction with the at least one processor or the at least one processor core, a set of one or more design rules; performing data checking and data preparation concerning alignment or positioning of one or more circuit component designs to create design rule-driven data related to an electronic design based at least in part upon the set of one or more design rules; and generating at least a layout portion that is correct-by-construction with respect to the set of one or more design rules by at least performing structured physical implementation on at least the layout portion of the electronic design based at least in part upon a separate design rule and the design rule-driven data, without performing any design rule checking for the layout portion.
