Path sensitization

摘要

For different delay models, the concept of sensitization can be very different. Traditional concepts of sensitization cannot precisely describe circuit behavior when the input vectors change very fast. Using Boolean process approach, this paper presents a new definition of sensitization for arbitrary input waveforms. By this new concept it is found that if the inputs of a combinational circuit can change at any time, and each gate's delay varies within an interval (bounded gate delay model), then every path, which is not necessarily a single topological path, is sensitizable.
