... of distance to the end points of the trace or distance to the FLI. Feature- based FI expands tool capability by correlating EOTPR waveform signatures to design elements. This becomes possible because the improvements on EOTPR tool resolution and sensitivity allow it to pick up the subtle design waveform...
