SD Ram Controller for MAX100
« on: December 20, 2017, 09:24:47 AM »
Hello - how do I create a controller for the 8MB SDRAM on the MAX1000 using Quartus?
Thank you
Steve

Hello,
Have you tried creating a system in Qsys? Then read/write your SDRAM controller via Avalon interface. I think you can then export the Avalon port out of Qsys.

Hi - I have not yet purchased a MAX1000 but I would like to purchase many. But for my application  - a camera - I will need the SDRAM. I think it can be difficult to get all the timings right so i was hoping a SD Ram controller had already been developed!
Thanks!

You can configure the SDRAM controller timing parameter in the Qsys (see attachment)
I was thinking of creating an example that includes SDRAM with MAX1000 board but not had time to do it yet.
If you'd need something to start with, follow the link in my other post.
