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...

I tried once to simulate QSYS block which included one custom component and one on-chip memory.

Normally I don't simulate QSYS, but that time when I created the simulation files, it showed me error msg related to the custom component but I did not investigate.

I compiled the files needed manually but after I ran the file msim_setup.tcl in altera modelsim.

After you run this file, you see some new commands in the command line of modelsim. Commands are like "elab" and some commands related to the compilation. After I compiled, I ran the command elab which started the simulation. I did not try to integrate the top QSYS module in a testbench. I manually forced the rst commands and the clk from the waveform viewer in modelsim.
