The cable parameter selects the cable to use for communicateing with the board.
|
|
At the time of writting, cable may be one of xpc3, xess, rtl_sim or vpi. xpc3
|
|
assumes a xillinx parallel cable 3, rtl_sim connects to a rtl simulator,
|
|
communicateing with it via files (slow), vpi connects to a rtl simulator via the
|
|
vpi (faster). The port parameter specified designates TCP/IP port address where
|
|
the server starts. Run jp1 without arguments for a list of cable specific
|
|
options.
