Ah well thank you for trying so much
And yes the sump logic analyzer is nice too using the old Spartan 3, if I recall. It works pretty well except I think the memory on it was rather limited but the clock speeds were up to 200MHz. I agree taking off the IC would be the best way but short of that, a oscilloscope or logic analyzer would easily do the trick without having to remove it. Or another way is using an xray machine used to check the solder quality of BGAs and the like. Buuut does anyone have one of those lol.
