Timing Requirements - Worst case Removal Slack

Hallo all,

I have a critical warning of Worstcase removal slack of -2.461.

From node: - altera_reserved_tck
To node:   pzdyqx:nabboc|pzdyqx_impl:pzdyqx_impl_inst|FNUJ6967

I am not sure if I should ignore this warning as the path is the open 
core plus logic and it should constrain itself and since it operates on 
the slow JTAG clock

So the reason I see the failures is that the logic isn't constrained and 
not necessarily true failing paths. Unfortunately those are randomized 
names so you can't add in your own constrains easily. Since I use OCP, 
maybe it shows up as a failing path.

Any suggestions? Should I ignore it or fix it?

Thanks!
