A method and system for modifying power rails of an integrated circuit having improved wireability. This is accomplished by initially generating a power railing design of the integrated circuit into a three-dimensional rail based model. Next, analysis of the design is performed as to placement of the power rails in relation to neighboring elements that affects a predefined wireability. Finally, modification of a segment of each power rail that affects wireability is performed so that required power supply to the neighboring elements (e.g., pins, rails etc.) remains unaffected.

Names of signals are propagated through a circuit design inside tuples, with each tuple including at least a signal name and a sequential depth. A tuple being propagated is added to a list of zero or more tuples currently identified with a circuit element, unless a tuple of the same signal name is already present in the list. If already present in the list, then propagation of that tuple is stopped. Propagation of tuples may also be stopped depending on user-defined limits, e.g. on sequential depth. Tuple propagation may be used, depending on the embodiment, to identify features of interest in the circuit design, e.g. (a) a point of convergence of differently clocked signals, (b) location of gray coders, and (c) location of synchronizers, by appropriate identification of circuit elements from which tuple propagation is to start, and by appropriate checks on lists of tuples that result from tuple propagation.
