Connecting SRAM direct to NIOS - DE2 board

Can I connect SRAM directly to NIOS? Under SRAM tree I have Cypress CY7C1380C SSRAM and IDT71V416 SRAM. I choose 2nd. one. and I can not connect directly SRAM. Must be connected to an Avalon bus?

Hi,

you have to add a tri-state bridge (Bridges and Adapters -> Memory Mapped -> Avalon-MM Tristate Bridge) to connect the sram. Connect the tristate master interface of the tristate bridge with the tristate slave interface of the sram.
