SRAM Connection problems in NiosII(Cyclone III)

[Altera_Forum]

Hi all, 

I am working on a project to port NiosII softcore processor, SRAM connected via a tristate bridge and a custom MAC into Cyclone III(EP3C25F324C8). I used Altera's SOPC builder to have it working but the problem i faced was in the pin assignment where ALTERA assigns its internal signals to the pins dedicated to SRAM's pins and i am not able to assign two of my SRAM's data pins.   I see this error on compilation.  Error: Can't place multiple pins assigned to pin location Pin_D1 (IOPAD_X0_Y27_N7)   Info: Pin data_to_and_from_the_sram_0[1] is assigned to pin location Pin_D1 (IOPAD_X0_Y27_N7)   Info: Pin ~ALTERA_ASDO_DATA1~ is assigned to pin location Pin_D1 (IOPAD_X0_Y27_N7)   but my datasheet holds the pin D1 for sram_dq1.    Can anyone help me out in this issue.   Many Thanks to all,    Jude.

You need to change the device settings in Quartus, to be able to use the DATA1 programming pin as a regular I/O after configuration.

Thank u so much... But can u just let me know what all modifications should i make in the device settings...

Go to the Assignments menu, click on Device. 

Then click on the "Device and pin Options" button, go to the "Dual-Purpose Pins" tab, select "Data[1]/ASDO" and change the value to "Use as a regular I/O".

It worked!!!... Thank You so much...I would be very happy if u can also help me in solving this issue... 

 After generation of the code built in SOPC and programming the device with the sof file, when i go into Nios IDE to run a hello world program it says "The Software settings associated with this project is damaged".   Can u help me out in this issue..   Many thanks...
