DE1 SDRAM in VHDL

Hello!

I know that this problem was discussed many times and I want to apologize for this but please answer to my post, it's very important to my project and I've looked everywhere and still haven't found what I was looking for.

does anyone have a sdram controller for de1 board in vhdl. I know that Altera provides sdram controller but it's in Verilog and I have to use VHDL.

Thank You for Your help and understanding.
