I try to use the opb/iba unit of chipscope to monitor the opb bus within a simple edk design. I took the chipscope lab example as start point. I am able to see the OPB signals in chipscope, but I can not set a trigger point. For example, I want to trigger at a certain address 0xFFFFXXXX. If I wait for the triggercondition, the behaviour is the same if no condition is set (like the immediate trigger button is clicked). Another problem is: I don't see assembly or c-source code in the listing window. Do I have to tell chipscope where it can find sources? What could be wrong?
In the lab example there are three control ports instantiated at the ICON unit while only two ports are connected. I have two control ports instantiated and connected, because ISE failed at the unconnected control port (in the map phase).
Any ideas? Frank
