Cyclone IV development kit , SRam and Flash under qsys

Hello,

I work on the Cyclone IV GX FPGA Development kit, i build a system on Qsys, with Nios II, tri_state_bridge, cfi flash and SSRAM.

But i don't find the good SSRAM controller, it isnot the same interface with the kit doc ( ssram_ban,ssram_bbn,ssram_clk,ssram_e1n..).

the SSRAM is GSI GS832018GT-200V.

thanks a lot

    I have the same problem. Maybe the cypress driver could work. Have you tested it ?

    I will try a mem_test to be sure.

    In the example kit ( "board_update_portal" example), this example uses for the ssram controller a generic tri-state controller , the same for the Flash.

    This example permits to read and write ot the SSRAM and Flash.

    That give a good example but in verilog . I work in vhdl :(

    I use the "ssram16_hw.tcl" file with sopc and it works. just copy the folder "ip" in your project.

    after installing the kit installations files, you will find it file in:

    \altera\11.0\kits\cycloneIVGX_4cgx150_fpga\examples\board_test_system\bts_config\ip\ssram16
