XC7A50T-cpg236

Hi all,

We have developed  a board using XC7A50T-CPG236 and Micron mt25ql128 memory IC for loading the RTL into FPGA at start-up. It worked well intially, however, after several read-write operations(few thousand atleast), the RTL seemed to have stopped functioning, ie, no response on the data lines. On re-programming it, it starts to work again, but fails after a while. Does anyone have any theory why the hardware would fail? I understand this is a vague question but if anyone has experienced FPGA/Memory system issues similar to what I have described here, your insight would be great.

Re: XC7A50T-cpg236

Hello @suvanb1987 

Did you performed any changes in your RTL design recently?

Are you using any evalution license based Xilinx IP? Reason for this query: https://www.xilinx.com/support/answers/42380.html

Re: XC7A50T-cpg236

could you let us know about your FPGA system working environment(temperature/automotive/aerospace related)? is the device you are using commercial grade or industrial grade? could you please check on your FPGA power system they remain same throughout the system functioning.

How many boards you see this issue?
