Abstract
An example apparatus includes: interface circuitry; and diagnostic circuitry configured to: determine a set of signal chains that may be used by an application, a signal chain in the set to include an ordered sequence of one or more circuit modules; identify a first signal chain from the set that was used by the application; and run, in response to a determination that the circuit modules in the first signal chain are idle, a diagnostic test on the first signal chain.
Claims20
An apparatus to implement safety diagnostics, the apparatus comprising:
- interface circuitry coupled to a plurality of circuit modules;
- and
- diagnostic circuitry configured to:
- determine a set of signal chains that may be used by programmable circuitry, wherein a first signal chain in the set of signal chains includes one or more circuit modules of the plurality of circuit modules;
- identify the first signal chain was used by the programmable circuitry;
- and
- run a diagnostic test on the first signal chain via the interface circuitry in response to a determination that the one or more circuit modules in the first signal chain are idle.
An apparatus to implement safety diagnostics, the apparatus comprising:
- programmable circuitry;
- a plurality of circuit modules;
- and
- diagnostic circuitry configured to:
- determine a set of signal chains that may be used by the programmable circuitry, wherein a first signal chain in the set of signal chains includes one or more circuit modules of the plurality of circuit modules;
- identify the first signal chain was used by the programmable circuitry;
- run a diagnostic test on the first signal chain in response to a determination that the one or more circuit modules in the first signal chain are idle;
- and
- provide a result of the diagnostic test to the programmable circuitry.
A method to implement safety diagnostics, the method comprising:
- determining, with diagnostic circuitry, a set of signal chains that may be used by programmable circuitry, wherein a first signal chain in the set of signal chains includes one or more circuit modules;
- identifying, with the diagnostic circuitry, the first signal chain was used by the programmable circuitry;
- and
- running a diagnostic test on the first signal chain with the diagnostic circuitry and in response to a determination that the one or more circuit modules in the first signal chain are idle.
