Abstract:
1. A computer-implemented method of propagating a signal through a representation of a circuit design, the method comprising: checking if an element in the circuit design is not currently identified with any signal passing through the element, to obtain a first result; identifying a first tuple with the element when the first result is true; wherein the first tuple comprises at least a name of said signal and sequential depth of the element through which said signal is being propagated; checking if the element in the circuit design is currently identified with at least another tuple, to obtain a second result; checking if every tuple currently identified with the element differs from the first tuple in the name of said signal when the second result is true, to obtain a third result; and identifying the first tuple with the element, in addition to every tuple currently identified with the element when the third result is true.
