Problems porting from 11.1 SOPC to 12.1 QSys.

I have recently opened my 11.1 design in 12.1, starting from an Archive (.qar file)

It contains an SOPC builder system, and I want to port it to QSys for various reasons.

I have encountered a couple of minor issues in doing this, but now have hit this problem.

Here is my current flow:

• Open Quartus, using the .qar as the project. ok.

• Open QSys from the tools menu. Select the MortonScaler.sopc file.

• This errors-out indicating that the DDR global resets are not hooked up. Hook them up to external ports to the QSys system. ok

• Hit Generate

• This errors out indicating that some custom source files (MeasureDVI.vhd, ru_wrap.v, sh4mbx_core.v, mbxcore.v) are not present. Somehow the archive did not include them. Add these files from the original. ok.

• Hit Generate again

• Now this errors out with the error:

Info: altpll_0: Error while generating MortonScaler_altpll_0.v : 1 : Error: DLL ("altpll_avalon") not found

child process exited abnormally

I have not managed to get past this issue in 12.1 QSys.

I have attached the qar file, and the missing HDL files that appear to be necessary to open the QSys project.

Any help is gratefully received.
