Random pattern resistant faults (RPRFs) are faults in a digital circuit that are not easily detectable using randomly generated test patterns. These faults can be caused by various factors such as process variations, aging, and environmental conditions.
RPRFs are particularly challenging to detect because they do not exhibit a consistent behavior and may only occur under specific conditions. This makes it difficult to design effective test patterns for detecting these faults.
To address RPRFs, various techniques have been developed such as built-in self-test (BIST), redundant circuitry, and error-correcting codes. These techniques aim to improve the reliability and fault tolerance of digital circuits, especially for safety-critical applications such as aerospace, automotive, and medical devices.
