You can also use Tcl commands to connect to a hardware server/target combination. For instance, to connect to the digilent_plugin target (serial number 210203339395A) that is managed by the hw_server running on localhost 3121, use the following Tcl commands:
connect_hw_server -url localhost:3121
current_hw_target [get_hw_targets */xilinx_tcf/Digilent/210203339395A]
set_property PARAM.FREQUENCY 15000000 [get_hw_targets \
*/xilinx_tcf/Digilent/210203339395A]
open_hw_target
Once you finish opening a connection to a hardware target, the Hardware window is populated with the hardware server, hardware target, and various hardware devices for the open target (see the following figure).
