SRAM K1B3216B2E on Cyclone III Development Kit

dear sopc experts,

has anyone used the 2 x 32mbit sram K1B3216B2E on altera cyclone III development kit or altera stratix III development kit?

my problem: i instantiated a sopc with an tristate bridge, where my sram-interface is the mm-slave. my sram-interface component is associated with the SRAMInterface.vhd.

can anybody tell me, what i've done wrong? because it doesn't work!

thanks in advance!

    Hello again i think that problem is quartus version. I can not explain

    why my project created in quartus 7.2 does not work well (i can not read/write to the sram?) and project with same settings created in quartus 9.1 works well.

    Maybe quartus 9.1 sram sopc builder component have some settings that are misunderstood in quartus 7.2.

    Hello m.hellmanns.

    Thanks for your help. you are right, pin assignments are incorrect. I used altera pin assignments because i believed that was reference. I made a mistake.

    SRAM_WAIT NOTE

    You should not use sram_whait signal because it is not connected in sram component HDL so you can leave it unconnect.

    I want and i will to add your reputation.

    Regards Marcin.
