SafetyChip: a time monitoring and policing device

Abstract	The SafetyChip proposes a strategy where parts of the effort invested in the formal verification during the development of a system can be reused during the system's operation. The strength in a formal verification of a system is that a system can mathematically be proven to fulfil certain requirements, e.g., timing requirements. The SafetyChip uses information from verification to monitor and police a system during run-time. The monitoring is done by surveillance of the applications communication with the run-time kernel. If deviance from the predefined verified behaviour is detected, the SafetyChip can signal (police) this in different ways, e.g., by generating interrupts the system can respond to.In our experiments we use systems written in Ravenscar compliant Ada code and have automated model extraction from source code to the models used to verify the system.This paper presents the functionality and design of the SafetyChip. Properties of an implementation of the SafetyChip are also presented.
