Abstract: A method and corresponding system are described for monitoring a first node in a communications network by a second node, where the first node has a single-channel design and is designed to execute a safety-oriented application. The second node has a dual-channel design, and a safety protocol is used for a data transfer between the first and second node. The second node determines at each of two consecutive time points a time value based on an internal timer, and sends each determined time value to the first node. The first node in response to each receipt of the time values determines a further time value based on a further internal timer. The first node compares a difference between the two time values from the second node with a difference between the two further time values from the first node, and goes into an error state depending on the comparison.

Abstract: Unavoidable physical phenomena, such as an alpha particle strikes, can cause soft errors in integrated circuits. Materials that emit alpha particles are ubiquitous, and higher energy cosmic particles penetrate the atmosphere and also cause soft errors. Some soft errors have no consequence, but others can cause an integrated circuit to malfunction. In some applications (e.g. driverless cars), proper operation of integrated circuits is critical to human life and safety. To minimize or eliminate the likelihood of a soft error becoming a serious malfunction, detailed assessment of individual potential soft errors and subsequent processor behavior is necessary. Embodiments of the present disclosure facilitate emulating a plurality of different, specific soft errors. Resilience may be assessed over the plurality of soft errors and application code may be advantageously engineered to improve resilience.
