BUGS AT SRAM DEVICE

HI,
I am using CYCLONE-II DSP Development Board for my coll project.. in project i need to use SRAM available on the board... i programmed in VHDL. i maintained all the requirment specified in the data sheet... but i am not able access SRAM... please tell me any thing extra i need to maintain... or how i can proced... thanks in advance..........

Hello,

How do you access the SRAM? What the specific problem? Can you post code from your controller?

thanks for reply...
THE following signals are required to access SRAM... and i am generating that but not getting.. content of the location
 

Re: BUGS AT SRAM DEVICE

It's not said in your post, but Cyclone II DSP Dev Kit is using Synchronous SRAM (SSRAM) rather than simple SRAM. Are you sure, that you understood the timing requirements of the device?

Generally, I suggest to record the waveform at all SSRAM pins with SignalTap II and check against the datasheet.
