Abstract
Official abstract text for this publication.
A design tool can implement phase algebra based design evaluation to efficiently evaluate a circuit design with a compact representation of numerous waveforms without simulating the individual waveforms. Instead of individual waveforms, the phase algebra based design evaluation employs compact representations of a group or set of waveforms. Phase algebra based evaluation constructs representations of a set of waveforms based on relationships among a devised set of functions that account for the various states of a signal over time, including transitions and glitches. A memorized-transition function, referred to herein as an M-function, indicates signal transitions over time.
First claim
Opening claim text (preview).
What is claimed is: 1. A method comprising: determining a sequence of signal transition representations associated with an input net of an indicated component in a register transfer level circuit design, wherein each signal transition representation of the sequence of signal transition representations represents a non-deterministic transition from a previous signal state to a set of one or more possible signal states; determining, based on the indicated component, an output sequ…
