I ran into a weird timing error today. I supposedly have a timing violation, but it is of zero time. Here is the screenshot. Any ideas?
I am compiling at 120MHz, as you can see from the 8.33ns requirement above.

That is really strange, would you be able to attach the code that produces this error?

The Xilinx log would also be helpful.

Unfortunately, the code is proprietary, or I would have posted it in the first place. I did keep the Xylinx log, but that, also, has a bit too much info in it. The original post was more of a fishing expedition to see if anyone else had ever seen the issue than a solution. I simply hit the recompile and got a good image the next time. I would be happy to open a service request and pursue this under NDA, since I have about a 50% success rate compiling this code.

Check the log to see if the timings not met are setup and hold timings. They are not going to show up in your report.
