DK-DSP-2S60N [INTEL]

The Virtual JTAG IP core allows you to create your own software solution for monitoring, updating, and debugging designs through the JTAG port without using I/O pins on the device, and is part of the On-Chip Debugging Tool Suite. It provides direct access to JTAG control signals routed to the FPGA core logic, enabling fine granularity of control and opening the JTAG resource as a general-purpose serial communication interface. The infrastructure extends the JTAG protocol for Intel-specific applications and user applications. You can instantiate up to 128 instances, and the hub arbitrates between multiple applications sharing a single JTAG resource.
