Compile Error / EPCS multiple pin problem in DE2-35

Hello, I am having trouble using EPCS16. Generating on NIOS II works well but I get this error when I try to do a full compile in Quartus "Error (176310): Can't place multiple pins as...

Hi,


The error mention Pin ASDO;


Error (176310): Can't place multiple pins assigned to pin location Pin_E3 (IOC_X0_Y34_N0) Info (176311): Pin ASDO is assigned to pin location Pin_E3 (IOC_X0_Y34_N0) Info (176311): Pin ASDO is assigned to pin location Pin_E3 (IOC_X0_Y34_N0)."


Hence, I suspect the ASDO pin was the cause of the error. Can you only change ASDO pin to "regular IO"?. Do not make changes to nCEO pin. Keep the nCEO pin just as it is from the start. Then try again. Still the same error?


Regards,

Aiman

    Thank you. I only mentioned ASDO in my previous message, but in fact, nCSO also has the same issue. In the first image, two errors are reported. I will provide information on both of these errors:

    Error (176310): Can't place multiple pins assigned to pin location Pin_E3 (IOC_X0_Y34_N0) Info (176311): Pin ASDO is assigned to pin location Pin_E3 (IOC_X0_Y34_N0) Info (176311): Pin ~ASDO~ is assigned to pin location Pin_E3 (IOC_X0_Y34_N0)

    Error (176310): Can't place multiple pins assigned to pin location Pin_D3 (IOC_X0_Y34_N1) Info (176311): Pin nCSO is assigned to pin location Pin_D3 (IOC_X0_Y34_N1) Info (176311): Pin ~nCSO~ is assigned to pin location Pin_D3 (IOC_X0_Y34_N1)

    Regarding your previous response, I can change the ASDO pin to AS input tri-stated. However, even if I compile it in its original state, the same issue still occurs.
