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
