Timequest reports setup violation in clock "n/a"

Clock Slack Endpoint TNS n/a -8.274 -233.269 I'm quite certain I have no signal called "n/a" in my device, so this must be something I did wrong in the constraints. Anyone see this...

Ah...

Yes, I do have set_max_delay & set_min_delay statements (as one of the tutorials suggested).

you mention that it ignores PLL phase shifts - would set_input_delay or set_output_delay work better for these cases? I'm trying to get an external RAM interface properly constrained, and need to have the phase shifts in there for it to work.
