I started ringing out the pins on our EP3C16Q240C8 we bought through a broker since they are not programming/coming out of reset.
Starting with pin 8 on a virgin device, I'm ringing out the ground pins under a microscope. I haven't rung EVERY ground pin, but so far I have seen that some do not connect to others. Pin 8 rings to: 16, 172, 67, 125, 193 Pin 8 DOES NOT ring to: 11, 62, 116, 130, 191 Does this make sense so far? I though GND would be GND inside the entire device.
