kaz is right that you should only be sampling data in the same domain as your signaltap. I have had cases where I need to get that data but also look at data in another domain. It would naturally fail timing, but I was fine with that and didn't bother cutting it. The data captured had to be carefully analyzed, since I knew I would be sampling during transitions, but it works.
