The evaluation tool employs graphics and text user interfaces, redesigned software and hardware fault tolerance templates, graphics model preprocessing and simulation, and analysis and postprocessing techniques to provide offline reliability and fault tolerance measures for proposed software and/or hardware systems. The automated fault tolerance evaluator (AFTE) tool set allows system designers and analysts to implement fault tolerance early in the design phase through a validated computer-aided engineering environment. If fault tolerance capability must be added to existing systems, AFTE provides rapid modeling and analysis capability to support retrofit design efforts. The library of widely used components and fault tolerance templates aids the rapid development of simulation models of design alternatives and easy incorporation of validated fault tolerance process models into the system model. The simulation and analysis capabilities enable the user to validate system designs, evaluate alternative designs, and point out areas of possible redesign.<<ETX>>","PeriodicalId":141205,"journal":{"name":"9th IEEE/AIAA/NASA Conference on Digital Avionics Systems","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134504165","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is noted that operational experiences in developing and using these automated testing techniques have highlighted the need for incorporating target system features to improve testability. Improved target system testability can be accomplished with the addition of nonreal-time and real-time features. Online access to target system implementation details, unobtrusive real-time access to internal user-selectable variables, and proper software instrumentation are all desirable features of the target system. Also, test system and target system design issues must be addressed during the early stages of the target system development. Processing speeds of up to 20 million instructions/s and the development of high-bandwidth reflective memory systems have improved the ability to integrate the target system and test system for the application of automated testing techniques. It is concluded that new methods of designing testability into the target systems are required.<<ETX>>","PeriodicalId":141205,"journal":{"name":"9th IEEE/AIAA/NASA Conference on Digital Avionics Systems","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121805364","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The signal processor, part of a spacecraft receiver designed to support uplink radio science experiments at the outer planets, organizes the connections between redundant arithmetic resources, register files, and memory through a shuffle exchange communication network. The configuration of the network and the state of the processor resources are all under microprogram control, which both maps the resources according to algorithmic needs and reconfigures the processing should a failure occur. In addition, the microprogram is reloadable through the uplink to accommodate changes in the science objectives throughout the course of the mission. The processor will be implemented with silicon compiler tools, and its design will be verified through silicon compilation simulation at all levels from the resources to full functionality. By blending reconfiguration with redundancy the processor implementation is fault-tolerant and reliable, and possesses the long expected lifetime needed for a spacecraft mission to the outer planets.<<ETX>>","PeriodicalId":141205,"journal":{"name":"9th IEEE/AIAA/NASA Conference on Digital Avionics Systems","volume":"2006 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128821424","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is pointed out that the procedures that guide the avionics software development and testing process are under increased scrutiny. The Radio Technical Commission for Aeronautics DO-178A guidelines, Software Considerations in Airborne Systems and Equipment Certification, are used by the US Federal Aviation Administration for certifying avionics software. To investigate the effectiveness of the DO-178A guidelines for improving the quality of avionics software, guidance and control software (GCS) is being developed according to the DO-178A development method. It is noted that, due to the extent of the data collection and configuration management procedures, any phase in the life cycle of a GCS implementation can be reconstructed. Hence, a fundamental development and testing platform has been established that is suitable for investigating the adequacy of various software development processes. In particular, the overall effectiveness and efficiency of the development method recommended by the DO-178A guidelines are being closely examined.<<ETX>>","PeriodicalId":141205,"journal":{"name":"9th IEEE/AIAA/NASA Conference on Digital Avionics Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121174445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
