Does Quartus generate a "Unused Signal" report for modules that it compiles?

Can Quartus generate a "Unused Signal" report for modules that it compiles? if so, how is it turned on and/or viewed?

    Hi,

    after running synthesis, should see the .syn.rpt being generated check screenshot attahced.

    Or in GUI, go to compilation report -> Synthesis -> Warning Messages

    compilation report -> Synthesis -> Partition "root_partition" -> Optimization Results -> Register Statistics -> Register Removed During Synthesis

    Check screenshot attached.

    Thanks,

    Sheng

    Hi,

    Can check the .syn.rpt in output_files folder under section Warnings for <module_name> and Registers Removed During Synthesis. Will have reasons like Pin "" is stuck at GND or Lost fanout.

    Thanks,

    Best Regards,

    Sheng

      Hi ShengN,

      I was not able to locate the *.syn.rpt file in the output directory or anywhere else in an of the other project directories. Does it have another name or is it located somewhere else?

      Thanks for your timely reponse.
