ID:268011 Pre-synthesis nodes should be added to partitions with a netlist type of Source File. See the Messages window for more information.

CAUSE: You assigned the specified pre-synthesis node to a SignalTap II File (.stp), but the SignalTap II Logic Analyzer is not in the incremental compilation mode. You can add SignalTap II post-fitting nodes only when the SignalTap II Logic Analyzer is in incremental compilation mode. This message is a submessage of the message that precedes it in the Messages window and Messages section of the Report window.

ACTION: Assign SignalTap II post-fitting nodes, or turn on incremental compilation for the current instance to insert SignalTap II post-fitting nodes.
