Efficient mechanism for interactive fault analysis in formal verification environment

Abstract:

In one aspect, a fault injection environment and a formal property verification environment are combined in a single integrated flow that allows the user to go back and forth between the two tasks. A system that unifies formal property verification and fault injection includes user interfaces that support the unified use model. In one approach, the FPV tool is the master and its user interface is the primary interface for the user to set up, run and debug faults as well as checkers. This interface allows the user to interactively select the FPV properties and/or the faults to be used for fault analysis. The user interface may provide a view of the faults, for example by listing faults or summarizing faults by class, type, etc.
