Abstract Classification Level
ConceptThe abstract classification level is the middle tier of a three-level errata classification scheme (concrete, abstract, and class) introduced in the RemembERR project. It represents a higher level of abstraction than the exact actions described in an erratum, sitting between the concrete action (e.g., 'the core resumes from the C6 power state') and the broad class (e.g., 'power management'). This level is crucial because design testing and validation tools must achieve generality to maximize coverage; considering only specific concrete actions (like transitions from the C6 power state) may miss unknown bugs that manifest when transitioning from other power states. The abstract level contributes to better generality while remaining more specific than the highest class level, enabling more general conclusions about bugs triggered by a particular trigger class.

Abstract Classification Level
Overview
The abstract classification level is one of the three tiers of the errata classification scheme used by the RemembERR project to classify microprocessor errata from Intel Core and AMD families (since 2008). The three levels, in increasing order of abstraction, are:
