issue upgrading Nios1 to Nios2

Hi all,

I am upgrading my legacy Nios1 project to Nios2 according to the instructions in Altera App Note 350. After regenerating my Nios2 CPU in the SOPC biulder, I tried to recompile my project in Quaturs II. But errors are encountered in the Analyse and Synthesis step, and I was shown the following error message:

Error: Can't compile project with SignalTap II instance "sld_signaltap:auto_signaltap_0" in unsupported SignalTap II IP version 3. Current SignalTap II IP version is 4.

Error: Can't elaborate inferred hierarchy "sld_hub:sld_hub_inst"

Currently, I don't need the signaltap analyzer in this project. Can anybody please tell me how to remove it or upgrade it to version 4.

Thank you very much!!

    I have solved this problem by unchecking the "Enable Signaltap II Analyzer" check box in "Signaltap II Logic Analyzer" in Quartus II Settings Dialog.
