Special Issue Information
Dear Colleagues,
Reliability is a growing concern for electronic digital circuits. This is especially relevant for applications working in harsh environments, e.g., space, in which radiation sources may induce several phenomena that can jeopardize the behavior of the system. However, in recent years, this issue has extended to other application fields working at the ground level, mainly because of the use of smaller geometries. In this case, devices become more sensitive, and errors sources are not limited to radiation, other causes being, e.g., the impurities in packaging or the use of reduced voltage levels in low power modes. In order to tackle this problem, fault-tolerant circuits are a must. Leaving aside rad-hard fabrication methods, protection by design is usually an interesting approach to achieve the desired reliability. From innovative uses of standard duplication and triplication techniques (as DMR and TMR) to ad-hoc reliable architectures, fault-tolerant design principles may be applied to a wide range of systems. These efforts are usually coupled with the protection of memories, using innovative error correction codes that increase the reliability of the applications. However, it is not only novel protection techniques that are necessary: Tools and procedures to rapidly test the behavior of the new reliable architectures are also needed. In this respect, the design and implementation of CAD tools that can emulate error injection in digital designs is another way to boost research on fault-tolerant circuits. Finally, the advent of reliable digital circuits is fostering the use of applications with a focus on fault tolerance in a variety of fields such as space, transport, biomedical, nuclear, and high energy physics. In this Special Issue, we are interested in exploring new protection techniques for electronic systems, CAD tools to perform reliability tests and novel applications, in different fields, which can benefit from the use of fault-tolerant circuits.
These topics include but not limited to:
- New protection techniques for digital circuits
- Fault-tolerant computer architectures
- Error correction codes (ECC) to increase reliability in innovative ways
- Signal and image processing systems with a focus on reliability
- CAD tools and methods to emulate error injection test processes
- Novel applications of fault tolerant digital circuits
