Honored ContributorHello Friends....is there anyway to read the data in the SRAM on altera DE2 board.....
i wrote a program to load the data into SRAM and to display it.....sometimes i am getting different resulty...so i just want to check whether the data is loaded into SRAM or not Regards, Gupta...
Honored Contributoryou might try SignalTap to diagnose the problem.
Honored Contributori didnt understand that what you said
Honored ContributorSignalTap is a tool in Quartus/the FPGA that can help you see what data is going in and out of the SRAM. its like a logic analyzer but integrated with the FPGA and software.
Honored ContributorGupta,
If you have access to an oscilloscope or actual logic analyzer, I would also recommend looking at your address/data lines in the "analog" domain if you are operating at any kind of reasonably high speeds. I have run into signal integrity issues before due to poorly designed development boards. Was only running at 50MHz, but whenever several address lines would transition at the same time, the transient would affect some of the data lines as well, resulting in incorrect data. for your reference...I am the reader who wrote in :) http://www.pldesignline.com/showarticle.jhtml?articleid=204805335
