not really so useful, but included is now script that creates ready to use dummy test bitstreams for existing ZYNQ devices, to allow immediate testing of XVC JTAG server software.

So take the XVC code from Xilinx github, use the ready made bitstream from LabX and you can check that the software and demon actually works. Sure the jtag server would send JTAG scan data to nirvana, but it would actually talk to the real IP core, so if it works with dummy, it would work with real hardware JTAG as soon as you as make the JTAG port extenal and assign the pins according your board.
