Why do I see netlist mismatches reported in the HardCopy Companion Revision Comparison Report related to the SignalTap II Logic Analyzer?

Environment

BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

Due to a problem in the Quartus® II software versions 11.0 and earlier, you may see netlist mismatches in the HardCopy® Companion Revision Comparison Report related to the SignalTap™ II Logic Analyzer for designs targeting HardCopy IV devices. Netlist mismatches may be reported if the order of assignments related to the SignalTap II Logic Analyzer are different in the Quartus II Settings Files (.qsf) files between the Stratix® IV revision and the HardCopy IV revision.

To work around this problem, reorganize the .qsf for the HardCopy IV revision by clicking Organize Quartus II Settings File from the Project menu before compiling the HardCopy IV revision.

This problem is scheduled to be fixed in a future version of Quartus II software.
