2. Stuck-at fault - Wikipedia

   en.wikipedia.org/wiki/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 generation to ...

3. Automatic test pattern generation - Wikipedia

   en.wikipedia.org/wiki/Automatic_test_pattern...

   ATPG (acronym for both automatic test pattern generation and automatic test pattern generator) is an electronic design automation method or technology used to find an input (or test) sequence that, when applied to a digital circuit, enables automatic test equipment to distinguish between the correct circuit behavior and the faulty circuit behavior caused by defects.

4. Fault model - Wikipedia

   en.wikipedia.org/wiki/Fault_model

   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 ...

   The impact of any latent fault tests, and The operational profile (environmental stress factors). Given a component database calibrated with field failure data that is reasonably accurate, [ 1 ] the method can predict device level failure rate per failure mode, useful life, automatic diagnostic effectiveness, and latent fault test effectiveness ...

7. Fault coverage - Wikipedia

   en.wikipedia.org/wiki/Fault_coverage

   In digital electronics, fault coverage refers to stuck-at fault coverage. [1] It is measured by sticking each pin of the hardware model at logic '0' and logic '1', respectively, and running the test vectors. If at least one of the outputs differs from what is to be expected, the fault is said to be detected.

9. Semiconductor fault diagnostics - Wikipedia

   en.wikipedia.org/wiki/Semiconductor_fault...

   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
