If I create a diagram and use the default delays tpd1 and tpd2, the Part_Delay definitions are not saved in the TIM file so when I reopen (or reload) the delays are missing from the diagram. The
usage of the delays
is saved, so I can edit the TIM file in a text editor to restore the Part_Delay definitions. If I "Reload" the file the delays re-appear.
BTW I've just come back to using TimingAnalyzer briefly after a long time away. I've tried other tools in the meantime, but for me none are as flexible as TimingAnalyzer. Great tool, thanks Dan.
