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?

Hi
I've assumed that with large areas of silicon you can't easily send the +5V or 0V around everywhere from a single connection without serious voltage drops - hence the need for several 5V and 0V connections. I don't know however if these 'assumed' sections of the silicon are connected - hence we checked that all the 5V connections were intact externally - but they may have fused internally. All conjecture, but the logic behind the thought that perhaps one of these siloicon areas had failed.
The module is quite simple - the only other part we can't check easily is a microcontroller, but currently the main suspect is the FPGA - we need to check this with the programming software now as we are scratching our heads!
I'll report back when we get to program or at least attempt to!
Cheers
