Techniques for analysis of an electrical circuit design are described, which techniques employ two phases: an initialization phase, and a check phase. During the initialization phase, a circuit design is examined to determine the predicted operating characteristics at various nodes within the design. If the design is hierarchically arranged, then the design is analyzed in a way that preserves its hierarchy. During the check phase, various implementations of the invention will check the determined operating characteristic values to see if they indicate that one or more design rules have been violated. A user may specify or "program" aspects of the analysis, both for the initialization phase and the check phase.
