Honored ContributorChecking FPGA for LE damage
Hello, We have a good reason to believe that an ACEX 1K FPGA on one of our board has some physical damage, i.e. some malfunctioning logic elements. Is there any standard way to test this ? I ca...

Honored ContributorI don't think that only one LE is damaged, I've never heared of such a case. If there is a damage, then more likely on the I/Os.
For me it sounds more like an asynchronous design issue where from the outside you believe that the device is damaged because it produces strange behaviour - in fact there are only some internally produced glitches which let the logic switch randomly. He should look at the design to make sure it's synchronous, check timing analyses... regards Daniel
