Modeling bridge fault. Bridging to VDD or Vss is equivalent to stuck at fault model. Traditionally bridged signals were modeled with logic AND or OR of signals. If one driver dominates the other driver in a bridging situation, the dominant driver forces the logic to the other one, in such case a dominant bridging fault is used.
Basic fault models in digital circuits include: Static faults, which give incorrect values at any speed and sensitized by performing only one operation: the stuck-at fault model. A signal, or gate output, is stuck at a 0 or 1 value, independent of the inputs to the circuit. the bridging fault model. Two signals are connected together when they ...
Bridging to VDD or Vss is equivalent to stuck at fault model. Traditionally both signals after bridging were modeled with logic AND or OR of both signals. If one driver dominates the other driver in a bridging situation, the dominant driver forces the logic to the other one, in such case a dominant bridging fault is used.
Various fault types may be applied to the diagnostic model. Commonly used fault types are: stuck-at faults, which simulates a node stuck high or low; stuck-open fault, which simulates a disconnected node; bridging faults, which simulate an unwanted connected between two nodes; transition-delay faults, which simulate slow signal switching on a node
Stuck-at fault. A stuck-at fault is a particular fault model used by fault simulators and automatic test pattern generation (ATPG) tools to mimic a manufacturing defect within an integrated circuit. Individual signals and pins are assumed to be stuck at Logical '1', '0' and 'X'. For example, an input is tied to a logical 1 state during test ...
IEEE 802.1. IEEE 802.1 is a working group of the IEEE 802 project of the IEEE Standards Association. It is concerned with: [1] 802 LAN / MAN architecture. internetworking among 802 LANs, MANs and wide area networks. 802 Link Security. 802 overall network management.
Failure mode and effects analysis (FMEA; often written with "failure modes" in plural) is the process of reviewing as many components, assemblies, and subsystems as possible to identify potential failure modes in a system and their causes and effects. For each component, the failure modes and their resulting effects on the rest of the system ...
A Byzantine fault is a condition of a system, particularly a distributed computing system, where a fault occurs such that different symptoms are presented to different observers, including imperfect information on whether a system component has failed. The term takes its name from an allegory, the "Byzantine generals problem", [1] developed to ...
