Hi all,
I am working on a video frame buffer which is using the cyclone 4E FPGA and the altera megafunction DDR2 SDRAM controller with ALTMENPHY. I am dealing with the streaming video data, thus I don't need the auto-refresh function in the DDR2 controller. is it possible to turn it off so that I may save some bandwidth? Thanks DanielLink Copied

Did you read the user manual? I think you'll set USER_REFRESH_EN to true and never request a refresh.

It may be the case that parameter isn't passed to the hp_controller instance. May be you need to edit the wrapper instance generics manually.
