It&#x27;s not a bogus argument. The author here is flat out incorrect. There are many bit-level resources on a modern FPGA which could be configured to both source and sink current on the same wire. Any transistors set in this mode most certainly will burn out, at minimum the wire track, but at maximum an entire region of the die.<p>EDIT: Modern process makes this problem worse actually, since wires are by definition smaller, decreasing their failure threshold. Even a short for a nanosecond can cause irreversible damage.
