1. Start xvcSrv on a machine with fast connectivity to the FPGA

     xvcSrv -t <target_ip>[:<udp_port>]

   A pre-compiled binary is installed here

     /afs/slac/g/reseng/xvcSrv/bin/<architecture>/
   or here
     /afs/slac/g/lcls/package/xvcSrv/<architecture>/
   

2. Start hw_server on the same or a close-by machine (no special arguments necessary); if you run Vivado on-site then vivado takes care of this step and you may skip step 3.
3. From remote (e.g., laptop) you might have to use an ssh tunnel to get to the hw_server. You can in fact use ssh to directly launch the server and tunnel the connection (assuming hw_server is on the PATH):
   

     ssh -L 3121:localhost:3121 gateway_machine  hw_server

4. On the remote machine launch Vivado and connect to the default target (since the ssh tunnel was opened on local port 3121 Vivado will find it)
5. In the Vivado hardware manager connect to the hw target:
   

     % open_hw_target -xvc_url  <machine_where_xvcSrv_runs>:2542

6. That's it. Vivado should find the new target. You will need to load the debug probe (.ltx) file and possibly "refresh" the target.
7. The initialization then takes quite a while (from my home it takes ~30s for the GUI to populate in the hardware manager) but further interaction (including display of waveforms) is acceptable.
