Here are some methods that can aid fault injection to efficiently explore the fault space to reach higher fault coverage in less simulation time. Sensitivity analysis: [ 9 ] In this method, sensitivity analysis has been used to identify the most important signals that have a higher impact on the system's specification.

David Vandevoorde first introduced the acronym SFINAE to describe related programming techniques. [ 1 ] Specifically, when creating a candidate set for overload resolution , some (or all) candidates of that set may be the result of instantiated templates with (potentially deduced) template arguments substituted for the corresponding template ...
MALPAS – A formal methods tool that uses directed graphs and regular algebra to prove that software under analysis correctly meets its mathematical specification. Polyspace – Uses abstract interpretation, a formal methods based technique, [17] to detect and prove the absence of certain run time errors in source code for C/C++, and Ada
Cyclic codes are not only simple to implement but have the benefit of being particularly well suited for the detection of burst errors: contiguous sequences of erroneous data symbols in messages. This is important because burst errors are common transmission errors in many communication channels , including magnetic and optical storage devices.
Fault detection, isolation, and recovery (FDIR) is a subfield of control engineering which concerns itself with monitoring a system, identifying when a fault has occurred, and pinpointing the type of fault and its location. Two approaches can be distinguished: A direct pattern recognition of sensor readings that indicate a fault and an analysis ...
Sometimes a timeshift (delay) is set between systems, which increases the detection probability of errors induced by external influences (e.g. voltage spikes, ionizing radiation, or in situ reverse engineering).
The construction of a failure detector is an essential, but a very difficult problem that occurred in the development of the fault-tolerant component in a distributed computer system. As a result, the failure detector was invented because of the need for detecting errors in the massive information transaction in distributed computing systems.
