Arria II I/O Modules

Hi everybody,

I'm working on an Arria II board on which we are trying to run a ddr3 SDRAM.

When I tried to fit the design I got some errors regarding the over bidirectional pin assignment in the I/O module.

I guess my board is useless now but to fix the next version I need to know how to properly assign the I/O pins and how to distribute them among I/O modules?

From where I can find out which pin belongs to which I/O module?

best regards,

Mocix

    I'm not sure I understand what you mean by an "I/O module". Do you mean an I/O bank? What are the exact error messages you are getting from the tool?

    Can you also show your pin assignments in the Pin Planner?

      Hi,

      thanks for your reply.

      I attached the screenshot which shows the errors and my pin assignments in the pin planner. Also, the CSV file exported from the pin planner.
