ID:19517 Quartus Prime partially connected Signal Tap or other In-System debug instance "<name>" to <number> of the <number> requested data inputs, trigger inputs, acquisition clocks, and dynamic pins. Please check the compilation report for more details.

CAUSE: The Quartus Prime software could not fully connect the Signal Tap or other in-system debug instance because some connections are invalid or unavailable. Dangling input ports on the debug instance will be connected to GND. If the input port is a data source, the captured data will always be GND. If the input port is a trigger, any dependent trigger conditions may be permanently disable or enabled. If the input port is an acquisition clock, the debug instance may not operate in hardware or respond through the JTAG port.

ACTION: See the report panel for more details on each invalid connection and possible corrective actions.
