Abstract
An apparatus includes operational circuitry and Hardware Diagnostics Circuitry (HDC). The HDC is configured to receive a definition of multiple trigger rules, each trigger rule specifying a respective trigger event as a function of trigger data sources in the operational circuitry, to receive a definition of (i) a pre-trigger logging set selected from among a plurality of diagnostics data sources in the operational circuitry, and (ii) for each trigger rule, a respective post-trigger logging set including a set of one or more of the diagnostics data sources, and, during operation of the operational circuitry, to log the diagnostics data sources in the pre-trigger logging set, to log the trigger data sources and to repeatedly evaluate the trigger rules, and, in response to triggering of a given trigger event by a given trigger rule, to start logging the diagnostics data sources in the post-trigger logging set of the given trigger rule.
