Formal Design and Veri cation of a Reliable Computing Platform For Real-Time Control Phase 3 Results

In this paper the design and formal veri cation of the lower levels of the of the Reliable Computing Platform (RCP), a fault-tolerant computing system for digital ight control applications, are presented. The RCP uses NMR-style redundancy to mask faults and internal majority voting to ush the e ects of transient faults. Two new layers of the RCP hierarchy are introduced: the Minimal Voting re n...

Formal Requirements Analysis of an Avionics Control System

|We report on a formal requirements analysis experiment involving an avionics control system. We describe a method for specifying and verifying real-time systems with PVS. The experiment involves the formalization of the functional and safety requirements of the avionics system as well as its multilevel veri cation. First level veri cation demonstrates the consistency of the speci cations whils...

Formal Verification of Real time Software

The veri cation of functionality of the input output logic properties often composes the majority of software requirements analysis Automated theorem provers ATPs such as SRI s Prototype Veri cation System PVS have been successfully used in the formal veri cation of functional properties However such functional methods are not readily applicable to the veri cation of the real time software re q...
