摘要: The subject invention features diagnostic circuitry installed on one or more chips of a board. This is constructed so that during interval it generates output signal if and only supplied with normal voltages service supply structures (such as ground, B+ supply, clock) distributing to devices the connected pin chip which may also serve operating pins input pin). receptacle for board interface at periphery
