For obfuscation, the unused diode footprints could be populated with decoys that look like diodes but are open. You wouldn't want the competition easily understanding your 30 byte diode program.
- zh3 2y agoWe used to fit all the diodes then use a pair of contacts connected to a high current supply to blow the unwanted ones. The diodes make (and still do) a nice little flash as the internal point contact blows. IIRC you could tell which ones were blown by close inspection (we weren't doing it for obfuscation though).
