I am trying to use chipscope to debug a simple design on the digilent spartan 3 starter board I insert a chipscope core using ISE 7.1 i synthesize my design and download it to the board via impact. now when I do analyze design using chipscope from within ISE chipscope starts, and I click the open cable icon in the upper left corner and the machine just sits for awhile, searching each LPT port (yes the parallel jtag cable is connected to the machine and the board) each of them time out i guess, and chipscope tells me:
ERROR: Socket Open Failed. localhost/127.0.0.1:50001 localhost java.net.ConnectException: Connection refused: connect ERROR: Socket communication not open.
any ideas?
do i need to have the full version of chipscope for this to work? (i may have an evaluation version)
thanks,
