MAX10m08 board SDRAM access example

Hi, I'm a student and new to FPGA design. I'm trying to access external SDRAM on MAX10M09 board via SDRAM controller. The main idea is to write into a certain address with a certain value...

Finally, I got it.

Several mistakes were made:

1. I didn't connect clock pin to DDR SDRAM. That pin was not created by 'SDRAM controller' module which was wired.... So I created one output pin on my top design to supply clock input to SDRAM.

2. The default reset signal in 'SDRAM controller' module was opposite of my top design. So everytime my top module was turned on but the SDRAM controller was off.

Thanks
