Cannot instantiate Chipscope

Hello!

 

I have problem with Chipscope PLBv46 Integrated Bus Analyzer (IBA) that I cannot resolve. I want to monitor the transactions on my PLB Bus, and there I have added the IBA IP and connected it to the PLB Bus. No matter what I do and how I connect the IP, I get the same error message during synthesis:

 

"Multi-source in Unit <chipscope_plb_iba_0> on signal <chipscope_icon_control<3>>"

 

In one way or another it seems to be multiple drivers on the "chipscope_icon_control(3)" signal when the IP is instantiated, but I do not understand why. I have also tried to make these signals external, and it does not change anything at all.

 

I am using Xilinx Platform Studio Version 9.2.i

 

Anyone who know what might be wrong or who have encountered the same problem?

 

Best regards

Olav T.

Re: Cannot instantiate Chipscope

Please show the connectivity of different bus connections of the chipscope core in your design to help.
