Hi,

I want to check some signal on USRP2 board. I inserted chipscope (ICON  
and ILA core) to u2\_rev3.v. At map stage, I received the error. Below is  
the error message.

ERROR: Pack:2310 - Too many comps of type “BUFGMUX” found to fit this  
device. (now design is using 9 out of 8 available).  
Can anyone suggest how can I reduce the usage of BUFMUX somehow? Thank  
you.

PN

Could you _not_ cross-post this stuff to the discuss-gnuradio mailing  
list?

Gnu Radio uses the standard, as-manufactured FPGA images, via UHD and  
gr-uhd, and 99% of the users of  
this list have no interest in modifying the FPGA code, nor can provide  
much assistance in the modification of  
that code, so posts on that topic here in this list just add noise.
