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.
