Review of Noise, Errors and Reliability in Digital Circuits

Digital systems are becoming more vulnerable to many types of noise, mistakes, and reliability issues as a result of the quick development of semiconductor technology and the increasing complexity of integrated circuits. The mechanisms that cause noise and mistakes in digital circuits, as well as the effects they have on the overall dependability and performance of the system, are thoroughly examined in this review paper. Important elements that affect logic integrity and timing behavior are examined, including crosstalk, electromagnetic interference, thermal noise, power supply oscillations, and process variances. The report also addresses the origins of many mistake types in deep submicron and nanoscale technologies, including as transient faults, soft errors, and permanent failures. A thorough study is conducted of methods for improving circuit reliability, including robust design-for-reliability approaches, faulttolerant design, error detection and repair schemes, and redundancy approaches. Additionally highlighted are new dependability issues in contemporary computer paradigms, such as lowpower, high-speed, and nanoscale devices. In order to guarantee the resilience and durability of upcoming digital systems, the review's conclusion highlights the significance of co-design approaches that incorporate reliability-driven and noise-aware design processes.
