Hi Mike,

I don't want to simulate it , because i have a 'double clocking' bug that
does not show up in simulation, this has to be a hardware probe, into
User_logic,.
These signals do not show up due to them being optimized out.

We are talking about direct injection of the chipscope core into the user
logic, not it sitting externally.
