Can an FPGA partially fail? (EPM7128SLI84-10)

Hi All, I have a production run of 110 plug in modules that each use a single EPM7128SLI84-10, two of these devices are suspected of failing as the modules show exactly the same fault in that 8...

From my understanding - an FPGA should just either work or not work. If theres something failing then I, like Kaz, assume it's a timing problem, or could it be other parts failed on the board?

There is no way to "lock out" a failed part of the FPGA as you would have no way to know which cells have failed, and I would assume more cells would just fail after.

Can you not just try a replacement/swapped board?
