Design Entry

Recently I have been having issues with project navigator in 13.4 that I can't explain.  If I make some changes to my design, XST, Implement, and Generate all show the question mark icon, and that makes sense.  Then I double click on configure target device, and it start the process way back at XST, and when it is done show the exclamation point, then it moves on to translate, map, and PAR within Implement and immediately goes back to a question mark after it is done running that stage.  I am not making any changes or touching Navigator at all, so why does it think something has changed?  This is frustrating because I have to start all over even if I didn't change anything.  I tried to restart the app and reboot the machine numerous times, but it keeps doing this.  Any thoughts?

Last time I checked, ISE used date & time stamping to determine if it needed to rebuild a source

file.  So for example if the last time XST was  run was at 9:00 AM and any HDL source was dated

later than 9:00 AM, XST would need to re-run.  If your source files are not on the same machine

as your project, then ISE is comparing date & time from two different systems.  If one system is

not set correctly (wrong time zone or time not set accurately) then it is possible for XST to complete

before the date stamp of its input files.  Then it will run again.

ISE Navigator also has another bug where it shows the question mark icons when it doesn't

need to rebuild, but as soon as you run a process the icons change to the proper status.  This

does not sound like your problem, though.

Good catch Gabor, that does appear to be the issue.  The code was hosted on a VM which seemed to get its time out of sink, that was causing all my issues.

Thanks for the help!
