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 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)."

 

 

I heard that this problem can be solved by setting Device-dual purpose pin-User as regular I/O, but even after changing the setting, I still get the same problem. I am attaching my error message and Verilog HDL file for reference.

 

 

I am using Quartus II 13.0spi / DE2_35 board.

My pin assignments are as follows, and I did it according to the DE2-35 manual. The DE2-35 Pin Assignment did not have pin numbers, but I found them in the circuit diagram, so I referred to that.

PIN_E3 -to ASDO

PIN_D3 -to NCSO

PIN_N6 -to DCLK

PIN_N3 -to DATA0

 

by the way, I changed the file extensions for some files to upload them. By removing the "txt" at the end, you should be able to use them.

Thank you for reading this.
