Test software design techniques for reuse and portability

A test station software, developed using LabWindows/sup TM//CVI/sup TM/, was implemented using a flexible architecture and modular design techniques in order to facilitate reuse and portability during the various stages of product development. The various software components-User Interface, Instrument Control, Data Collection, and Results Analysis-were partitioned into independent sub-units with limited end clearly defined interfaces between each other. This eliminated the coupling of software modules across software components. A test station configuration software component was also designed to centralize access and distribution of test station data.
