Abstract

Describes the Centurion computer-aided software fault tolerance design and analysis tool. The tool is a product of a research and development project focused on automated tools for use in design, assessment, and insertion of software fault tolerance techniques into Air Force systems. The Centurion tool allows users to analyze developmental and fielded software, and the associated computer and communications hardware, to identify fault tolerance requirements and evaluate alternative fault tolerant designs. The Centurion capabilities include interactive graphic construction software, hardware, and fault tolerance models; storage and retrieval of template and model libraries; simulation of the constructed models, with data logging and run-time user inputs permitted; and post-processing with tabular and graphic output formats available. Actual software modules can be associated with nodes within Centurion graphs and linked into the model simulation. The current Centurion tool is available on Sun SPARCStations, and is currently being ported to DEC Alpha workstations.<>
