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...

Yesterday I used the megawizard, it looks different from how it used to in earlier versions of the Quartus II. It looks like we are creating a Qsys component now.

Basically, I was going to do some basic simulation with the memory controller. However, I found that the tool generates several files, some of which look like tcl scripts and there is a folder named synthesis and another named simulation and there is some script called msim_setup.tcl. I am not sure how I can just go ahead into a VHDL testbench, instantiate the memory controller and start playing with it. I am confused. I am not trying to ModelSim simulate a Nios II system, its just a single memory controller on its own.
