Hi
I have downloaded a reference design (PCIe to External Memory) for arria ii gx. I am trying to reinstantiate and regenerate and recompile the design. However, it fails during fitting. The errors are as belows: Error: Can't turn on open-drain option for differential I/O pin mem_dqs[1] Error: Can't turn on open-drain option for differential I/O pin mem_dqsn[1] I can't anything in the design related to open drain. Any clue? ThanksLink Copied

I do run the script. After running the script, my .qsf is different from the .qsf of reference design. The error still exists.
Currently what i do is i copy assignment in the .qsf of reference design to my .qsf.- Mark as New
