Conditional phase algebra for clock analysis

Abstract

A design tool can implement phase algebra based design evaluation to evaluate a circuit design with a compact representation of numerous waveforms without simulating the individual waveforms. The design tool can determine two or more input sequences of signal transition representations associated with an input net of an indicated component in an RTL circuit design, where the two or more input sequences of signal transition representations are associated with a mode element. Each signal transition representation represents a nondeterministic transition from a previous signal state to possible signal state(s). The mode element indicates a selection between two or more output sequences of signal transition representations. It is determined, based on the indicated component and the mode element, two or more output sequences of signal transition representations derived from the input sequence(s) of signal transition representations.
