Several of these projects are taken as case studies to illustrate the difficulties encountered and the techniques used to deal with them. Four types of projects are considered: rehosting the MOS (MATE operating system) to a new 1750 A platform with various peripheral suites (systems have been Multibus based and VMEbus based); porting the MTE (MATE test executive) to a VAX/VHS environment; porting the MAC (MATE ATLAS compiler), MOLE (MATE on-line editor), and MTE to a 80286/Xenix environment; and porting the MAC, MOLE, and MTE to a 80286/DOS environment. Each project is analyzed in terms of work inherently necessary by the nature of the task, work made necessary by peculiarities in the target environment, and work associated with the development environment. Timesaving techniques used during development are highlighted. A special subsection is included which discusses the advantages that could have been realized had the original work been done in Ada. The application of Ada in the port process is also discussed.<<ETX>>","PeriodicalId":321804,"journal":{"name":"IEEE Automatic Testing Conference.The Systems Readiness Technology Conference.

APU Maid is initially being demonstrated on flight line hardware. The maintenance environment includes among its components an artificial intelligence (AI) based diagnostic system, an automated technical information system, and a maintenance management system. The diagnostic system is built on a core of diagnostic knowledge sources that include an event-based system function model, a structural model, symptom/fault information, and a wide range of logistics data. This core diagnostic model is designed for generic application to any electromechanical system including engines, flight controls, landing gears, and transmissions. It can also be applied to electronic systems, including avionics. The project objective is described, and the APU Maid components are described in detail.<<ETX>>","PeriodicalId":321804,"journal":{"name":"IEEE Automatic Testing Conference.The Systems Readiness Technology Conference.

Extending VXIbus systems across multiple-mainframe 跨多主机扩展vxi总线系统

{"title":"Extending VXIbus systems across multiple-mainframe","authors":"R. Wolfe","doi":"10.1109/AUTEST.1989.81125","DOIUrl":"https://doi.org/10.1109/AUTEST.1989.81125","url":null,"abstract":"There are currently three system configuration approaches to integrating a host CPU into a VXIbus mainframe system. These approaches involve the use of the standard general-purpose interface bus (GPIB), embedding a CPU module directly on the VXIbus, and use of a transparent, high-speed communication link. The author discusses each technique in detail and how each can be extended into a multimainframe system. It is noted that GPIB-to-VXI interfaces allow a mainframe full of VXI instruments to be treated as traditional GPIB instruments. Alternatively, MXIbus can be used to extend transparently the VXIbus itself to multiple mainframes that can be programmed as a single VXI system with many slots. Key software issues in a multimainframe configuration are the architecture and methodology of the software drivers through which the communication with the VXI instruments is actually accomplished and the resource manager capabilities and requirements imposed by the system.<<ETX>>","PeriodicalId":321804,"journal":{"name":"IEEE Automatic Testing Conference.The Systems Readiness Technology Conference.

Interfacing to boundary scan chips for system level BIT 接口到边界扫描芯片的系统级比特

He also shows how to bridge the protocol gaps between the various scan design devices (e.g. LSSD, boundary scan, and VHSIC) to arrive at an integrated built-in test and diagnostics strategy. It is concluded that the only way to achieve the fault detection and fault isolation requirements for the system is to design each card to be fully testable. Each designer could configure the circuit in any way desired and use any mix of components. The only rule is to have testability circuitry that can communicate with a standard testability bus interface on each card so that the system BIT (built-in-test) processor can perform its tasks.<<ETX>>","PeriodicalId":321804,"journal":{"name":"IEEE Automatic Testing Conference.The Systems Readiness Technology Conference.

Nemeth-Johannes","doi":"10.1109/AUTEST.1989.81144","DOIUrl":"https://doi.org/10.1109/AUTEST.1989.81144","url":null,"abstract":"The author describes the features of the Test and Measurement System Language (TMSL) and how they relate to compatibility. TMSL implements a tree-structured command set, rather than a traditional flat instrument language, allowing keywords to be reusable and identifiable in context. Reusable keywords allow for simple and regular mnemonic generation rules. TMSL has also addressed parameters through the use of regular parameter forms, a say-what-you-mean philosophy for discrete switch setting and the minimization of obscure side effects. TMSL addresses the need for horizontally compatible, signal oriented measurements, as well as the traditional programming of the specific instrument-specific hardware. The author also discusses a model of an instrument developed for TMSL and the importance of such a standardized model. He outlines the advantages realized, including the ease of adding capabilities in the future, the ease of learning, the self-documenting features, the opportunities for reuse of instrument firmware including increased reliability of parsers, and the ease of integrating instruments into existing test systems.<<ETX>>","PeriodicalId":321804,"journal":{"name":"IEEE Automatic Testing Conference.The Systems Readiness Technology Conference.

The UATL was rehosted to an HP Model 9000/Series 300 processor, and a set of test program generation and soft panel instrument control functions were added. HP's interactive test generator (ITG) includes ASCII instrument driver files that characterize the instrument functions and define interactive soft-panel control screens for developing test programs in BASIC. UATL/Ada-based instrument and operator screen control procedures have been written that provide similar functions for generating test programs in Ada. UATL provides a complete set of test support functions in Ada for performing closed-loop testing of a unit-under-test through its external interfaces. In addition to the instrument control functions, the UATL provides real-time digital stimulus/response controls over software or hardware interfaces, online test control and performance monitoring, data recording, and both ASCII and graphical data reduction. Ada introduces the advantages of portability and reusability, extensive data consistency checking, and built-in multitasking support.<<ETX>>","PeriodicalId":321804,"journal":{"name":"IEEE Automatic Testing Conference.The Systems Readiness Technology Conference.

RADC has sponsored several efforts under the smart BIT heading whose emphases have been to improve the ability of BIT to make more robust decisions based on knowledge of the situation rather than using a simple GO/NO trigger mechanism. This knowledge comes from various sources, including internal functions, external environment factors, and temporal monitoring. This knowledge has been captured and used by means of various AI and related techniques. Particular attention is given to the implementation of temporal monitoring software and to the smart BIT for Joint Surveillance Target Attack Radar System (Joint STARS).<<ETX>>","PeriodicalId":321804,"journal":{"name":"IEEE Automatic Testing Conference.The Systems Readiness Technology Conference.

The modified system provides test capability for large and complicated optics that are not supported by commercially available transmission test systems that test only witness samples or small optical assemblies. The modifications to the commercial hardware and software are described. Illustrations are given for single- and double-pass measurements of various optical systems. The performance capabilities of the new system are described along with methods used to validate the results. The usefulness of the new system is demonstrated by showing how systematic measurements on a complicated infrared imaging lens system were used to identify specific corrective actions. Measurements at the system and subsystem levels provide three unique optical system diagnostic capabilities: measurement of degradation due to time and environmental effects; system-, subsystem-, and component-level troubleshooting; and improved measurement accuracy by preventing error accumulation for multiple-element optical assemblies.<<ETX>>","PeriodicalId":321804,"journal":{"name":"IEEE Automatic Testing Conference.The Systems Readiness Technology Conference.

{"title":"Two-level maintenance concept for advanced avionics architectures","authors":"Kevin C. Judge","doi":"10.1109/AUTEST.1989.81102","DOIUrl":"https://doi.org/10.1109/AUTEST.1989.81102","url":null,"abstract":"The advanced avionic architecture for next-generation military aircraft will feature common signal- and data-processing modules. The common modules will incorporate VHSIC technology and feature extensive built-in-test (BIT) and error logging capabilities. These new technologies present an opportunity to eliminate the intermediate level of maintenance because self-diagnosed modules can be routed directly to the depot. The author describes a support philosophy which, through BIT capabilities and a factory/depot tester architecture, makes the two-level maintenance concept possible. He explains how to exploit the modules' ability to test themselves and the resultant effect on the support equipment requirements. He then discusses a MATE implementation of the depot tester and addresses issues such as hardware/software modularity, the selection of the controller and instrumentation, and the use of ATLAS versus Ada as the test program language.<<ETX>>","PeriodicalId":321804,"journal":{"name":"IEEE Automatic Testing Conference.The Systems Readiness Technology Conference.
