When I select "include only" on four nets, known to be constrained by an associated constraint that was analyzed, Timing Analyzer reports that zero items were analyzed. These nets are constrained under a constraint and should be analyzed. Why are they not "included"?
The four nets tagged as "included" nets should produce the correct path in question, but Timing Analyzer "ands" all of the nets and searches for a path that contains all of the nets. This is why Timing Analyzer returns zero items analyzed. You can work around this issue, by creating separate reports with individual nets in each report.
