11.4 Timing Analyzer - OFFSET OUT table in the Data Sheet Report shows different smallest/largest SLACK values than the SLACK column


In the Data Sheet section of the timing report, there is an OFFSET OUT table reporting the skew for an OFFSET OUT constraint. The smallest slack and largest slack values reported do not correspond to the numbers in the Slack column of the OFFSET OUT data sheet report table.


The numbers in the Slack column of the OFFSET OUT table are delay values, not slack values. The smallest and largest slack reported above the table are actual slack numbers. This is why you cannot find the smallest slack and largest slack values in the table. If you take the smallest slack and add it to the largest value in the Slack column of the table, you will get the requirement value of that OFFSET OUT constraint. Similarly, if you add the largest slack with the smallest number in the Slack column, you will again get the requirement.
