2. SSH Tunnels and the JTAG Server
The Intel® Quartus® Prime JTAG Server communicates with your FPGA hardware and allows multiple Intel® Quartus® Prime tools to use JTAG resources at the same time. Typically, the JTAG Server is run automatically as a Windows service or a Linux* daemon.
By default, the JTAG Server listens to TCP/IP port 1309, and JTAG client applications connect to the same port.
