Yes I am using XPS 14.6. But the problem is to open both Chipscope and to run the program simultaneously. I can run them separately quite well. Might it be a problem with bit stream that I am programming my FPGA or somthing else!? I generated the bit stream from the XPS 14.6 using the reference design from fpgahdl_xilinx/cf_xcomm_zed at master · analogdevicesinc/fpgahdl_xilinx · GitHub
