how can I use sdram

--- Quote Start ---

I want to make sure that this solution you provided is pure Verilog (There is no NIOSII).

Because I saw a SOPC builder.

Do you wish to write owner sdram controller (in verilog)?

I only need a Verilog module that is able to write into the SDRAM without NIOS.

NIOS is only part of SOPC facilities. I would recommended to read quartus. embedded peripherals (http://www.altera.com/literature/hb/nios2/n2cpu_nii5v3.pdf)

Please, if you can illustrate it a little bit for me, it will be very helpful for me.

Look at attachment. It`s only piece of my project (verilog), summary:

1. exten device (camera. without file) -> fifo -> controller_sops (without verilog) -> sopc_sdram_0 -> sdram

2. sdram -> sopc_sdram_0 -> controller_sops (without file) -> uart

note: in sopc_sdram_0 there are 2 no coupled part (1-write sdram, 2 - read sdram)

of course, it`s only part exampl, but i think it would help you.
