Abstract: Techniques are disclosed for combining diagnostic features at different levels (with a special consideration of the application-oriented measures) though a quantitative analysis that provides evidence supporting a claimed diagnostic coverage (DC) calculation for circuits to meet defined functional safety standards. These techniques implement a parametrized approach to allow tuning by a system integrator according to its specific software application environment. The required safety level or DC goals may thus be attained based upon the results of the safety analysis (and failure rates) provided by a device manufacturer.

Abstract: A fault detector has a processor configured to receive, during a register write event, first data that are to be stored on a first register; determine a first encoded value from the first data using an encoding operation; receive second data from the first register from one or more bit locations on which the first data were to be stored; determine a second encoded value from the second data using the encoding operation; and compare the first encoded value and the second encoded value. If the first encoded value is the same as the second encoded value, the fault detector operates according to a first operational mode; and if the first encoded value is different from the second encoded value, the fault detector operates according to a second operational mode.

Abstract: Technologies for ensuring functional safety of an electronic device include receiving data by a primary and secondary hardware unit and performing a function on the data. Each of the primary and secondary hardware unit perform the same function on their respective set of data to generate corresponding results. A determination is made whether the hardware units are synchronized and the results can be compared. If so, the results are compared and an alert is generated if the results do not match.

Abstract: In embodiments, a system may comprise a circuit component to perform a function; and a supervisor component (e.g., a safety component) coupled to the circuit component to monitor proper functioning of the circuit component. The circuit component may be configured to initiate provision of diagnostic information to the supervisor component, or to indicate to the safety component whether the circuit component will be responsive to a query from the safety component for diagnostic information.
