Odd error in timing analyzer

I am trying to look at a failed timing path in the floorplanner and I expected to be able to click on a link in the timing report and be taken to a selected net, logic or the entire path depending on the link. Instead it reports some errors about not being able to open a socket and crashes with the following error message...



FATAL_ERROR:GuiUtilities:WinApp.c:710:$Revision - This application has discovered an exceptional condition from which it cannot recover. Process will terminate. ...



The timing analyzer terminates. Anyone know what this is about?

ISE (like a lot of other tools) uses IPC between it's various tools. I noted that in an earlier thread you had certain things blocked at the firewall - ISE can croak if it doesn't have sufficient access rights (because rather than use the localhost convention they use your actual IP - gethostbyname and so forth - this is very common [1]) then it will just die because the code does not trap for the failure.

You may need to permit it some internet access even though it really want to merely communicate with some other process on the same system.

[1]. The Cadence tools (OrCad, Allegro, Spectra) do exactly the same. In fact, these need to be *internet servers* to operate properly - a real pain.
