ChipScope is a great tool, but, if I am not mistaken, it can work only 
if there are enough resources left on the host FPGA. So, as the  
resource utilization of the targeted FPGA increases, shouldn't chipScope 
be expected to be less and less capable because there would be fewer and 
fewer unutilized resources available to it?
