Not sure exactly what you mean by that, but iMPACT supports only certain specific cables.  For
example, the JTAG-USB cable is NOT supported by iMPACT.  The Spartan-3E can be programmed with the
USB cable it came with (I don't know if there is anything special about it - I think it's just a
standard cable) OR it can be programmed with a Digilent Parallel-III cable when plugged into the
board's JTAG port.
