Using Qsys SRAM and SDRAM controllers without a Nios II

I need to communicate with the SRAM in the DE2-115 board using purely VHDL code. No Nios II. Later I may have to use the SDRAM instead if bigge memory is required. I understand that a controlle...

Yes, the wires of the Avalon-MM interface can be exported similarly to how you would export a conduit.

The SRAM "controller" should be trivial and you could simply implement that directly in your VHDL. The SDRAM controller would be the primary motivation to involve Qsys/Avalon-MM in your design.
