Hi Vicky,

I'm converting from the following Quartus Prime version. That is the only one I can download.

Hi Abe,

I looked up the KDB link which talks about Quartus-II tool and provides the following explanation. I am not sure how much of this applies to Quartus Prime or Pro editions.

"These errors indicate a conflict in files generated for multiple IP cores. Each IP core should be compiled into its own design library as indicated in its Quartus II IP (.qip) file. If you see these errors, verify that your Quartus II Settings File (.qsf) file only calls out the .qip files for each IP core. You should not include any of the files listed in the .qip file directly in the .qsf."

I see the following line in .qsf file. I also have pll directory where there is .qip file. Not sure if this causes conflict.

set_global_assignment -name QSYS_FILE pll.qsys

I was expecting the tool to clean up everything as I didn't generate the .qsf file.
