Software architecture for building

Test system developers can benefit greatly from a software architecture that allows for easy interchangeability of instruments in those systems. Using open industry standard software architectures such as Virtual Instrument Software Architecture (VISA), and Interchangeable Virtual Instruments (IVI), developers are able to create systems with interchangeable test instrumentation. This paper describes the VISA and IVI software standards and demonstrates how their use within a broader software architecture, which includes standard development environments and flexible test executive software, facilitates the creation of interchangeable test systems     

Using interchangeable virtual instrument (IVI) drivers to increasetest system performance

Instrument driver technology has evolved tremendously over the last decade. Initiatives such as SCPI and VXIplug&play have simplified remote instrument programming with standardized command messages and high-level utility functions. The latest initiative is the Interchangeable Virtual Instrument (IVI) Foundation. IVI defines standards for instrument drivers that offer benefits to provide higher performance. These benefits include instrument interchangeability, instrument simulation, and instrument state-caching. Because instrument drivers are an integral part of a modern test system, IVI promises to provide developers with the tools to increase their system performance significantly. This paper reviews the technical aspects of the IVI specification and the TVI architecture and describes how IVI can help the test system developer improve performance and lower long-term software maintenance costs     

Re-hosting test program sets effectively and affordably [formilitary ATE application]

This paper describes an innovative process for re-hosting test program sets from an existing tester for which they were originally prepared to operate on another tester. The process greatly reduces the time and cost usually required for offloading a test program set while retaining most of the original design and interface hardware     

Integrating VISA, IVI and ATEasy to migrate legacy test systems

New software technologies, such as VISA and IVI, continue to bring the industry toward greater standardization. The benefit to the integrator is reduced costs through reuse of the same hardware and software. The benefit to the customer end-user is lower costs by reducing modification and support through the life-cycle to the test station. However, while we position ourselves for the future with PXI and these software technologies, we must still provide support for VXI, GPIB, and instrument drivers that use current software technologies. Using a number of additional tools such as National Instrument's Measurement and Automation Explorer and Geotest's ATEasy, we can have the power of these tools today while waiting for wider acceptance and support of the newer VISA and IVI technologies. We are just now seeing the development of IVI drivers and the ink is still wet on the VISA specification for PXI. ATEasy provided the structure necessary to use these technologies with the current technology. This paper explores the process of implementing and integrating the system driver and instrument drivers for a PXI-based test station for the TOW2 optical sight sensor.

Instrumenting embedded test software in support system integration, factory production, and depot repair

Embedded built-in test (BIT) software typically provides a system-level go/no-go indication and, in the presence of a failure, may provide some level of sub-system isolation. This level of reporting, while meeting the customer's operational requirements, does little to support system integration, production, and repair. To support these other needs, "instrumentation code" is added to the BIT software to provide detailed test data through an external interface. Since the BIT software already accesses the hardware parameters for testing, it becomes the most logical component for the instrumentation. This paper describes the techniques of embedding instrumentation during BIT design and development to support a broad range of program test needs. It explains the costs and benefits associated with the use of instrumentation. It gives specific examples of instrumented software and describes how instrumentation data can be used during environmental tests, factory test, and depot test. The impact instrumentation has on software development time, code size, execution time, and reliability is discussed as well as the cost of retrofitting BIT software to add instrumentation. Some of the benefits as well as the challenges to developing effective embedded instrumentation is also examined.
