Abstract

The Flexible Test System was developed to address two main areas that drive test equipment costs: new design costs and re-usability. In the past, development programs required uniquely designed test equipment for use during integration and certification testing. This equipment was designed from the ground up with little commonality from program to program. The test equipment was not reusable, and significant design costs were incurred with each new program. The Flexible Test System was designed using a two-tier documentation strategy consisting of a Base Test System - 100% reusable from program to program coupled with program-specific design additions. The Base Test System is illustrated in the Figure.

Flexible Test System for Processor Integration/Certification

      The Flexible Test System was developed to address two main
areas that drive test equipment costs: new design costs and
re-usability.  In the past, development programs required uniquely
designed test equipment for use during integration and certification
testing.  This equipment was designed from the ground up with little
commonality from program to program.  The test equipment was not
reusable, and significant design costs were incurred with each new
program.  The Flexible Test System was designed using a two-tier
documentation strategy consisting of a Base Test System - 100%
reusable from program to program coupled with program-specific design
additions.  The Base Test System is illustrated in the Figure.

      The Flexible Test System uses the industry standard VXI (VME
bus Extended for Instrumentation) interface for all input/output
cards.  This allows us to change card population readily.  Cards are
removed/inserted from the front of the rack.  Many types of interface
cards are available commercially, and unique cards are developed as
needed.  The power system is also designed with adaptability in mind.
The commercial supply uses pluggable modules for output changes, and
the modules are wired to a custom rear panel for cable connections.

      The Base Test System, which is a combination of commercial and
IBM-developed equipment, consists of a 6-foot-tall 19-inch-wide
industry sta...
