Abstract
In the systems and methods, an identifier is generated for a printed circuit board (PCB), chips are connected to the PCB, and corresponding sets of programmable bits on the chips are programmed to match specific sections of the identifier. Due to the generation of the identifier and the programming of the corresponding sets of programmable bits on the chips to match specific sections of the identifier, the validity of the chips can be verified at any time during product life. For example, for each chip, its set of programmable bits can be read and, then, a determination can be made as to whether that set of programmable bits is indeed programmed to match a specific section of the identifier. Operation of the PCB can be allowed when all the chips are determined to be valid and prohibited when any of the chips are determined to be invalid (e.g., previously used).
