ID:12040 Can't connect pre-synthesis signal "<name>" to port "<name>" on Signal Tap instance "<name>" because the signal does not exist in the pre-synthesis netlist

CAUSE: The specified input signal to the specified Signal Tap II instance does not exist in the initial netlist extracted from the source files in your design, also known as the pre-synthesis netlist. You may have modified your design since you created the Signal Tap II instance, or you may be attempting to tap a signal that exists only in the post-fitting netlist. The Quartus Prime software will connect the corresponding port on the Signal Tap II instance to GND.

ACTION: Verify that the signal exists in the Signal Tap II: pre-synthesis filter in the Node Finder. If you removed the signal from your design, then remove it from the Signal Tap II instance as well. If you need to tap a node that only exists in the post-fitting netlist, then add it from the Signal Tap II: post-fitting filter in the Node Finder. However, you can only tap post-fitting nodes if you have enabled Full incremental compilation.
