The Remote Signal Tap logic analyzer provides real-time hardware
debugging for the Accelerator Function Unit (AFU). It provides a signal
trace capability that the Quartus® Prime software adds to the AFU. The
Remote Signal Tap logic analyzer provides access to the Remote Signal
Tap part of the Port MMIO space and then runs the remote protocol.
