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

CAUSE: The specified input signal to the specified SignalTap 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 SignalTap 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 SignalTap II instance to GND.

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