Versions:
IVI Shared Components, published by the IVI Foundation, is a software package that supplies the common components shared by IVI-compliant instrument drivers and the applications that call them. Currently available at version 3.0.3, the catalog lists a single release of the package, which serves as a foundational prerequisite for test and measurement environments that rely on the IVI (Interchangeable Virtual Instrument) standard. Its purpose is to provide common services that both instrument drivers and their calling applications depend on, ensuring consistent behavior across IVI-compliant software. Among the components included are the IVI Configuration Store, which maintains configuration information used by drivers and applications, and the shared installation infrastructure that supports the deployment of IVI software on a system. Because drivers and applications rely on these underlying services, the IVI Shared Components must be installed before installing IVI instrument drivers, making the package a prerequisite in the installation workflow for IVI-based test systems. In terms of relevant categorization, the software falls within the category of instrument driver support components and shared runtime infrastructure for test and measurement software, aligning with developer and engineering tooling used to build and operate automated test applications. Typical use cases include preparing a workstation or test system to host IVI-compliant instrument drivers, enabling applications to access standardized driver services through the shared infrastructure, and maintaining a central configuration store that drivers and applications can reference for consistent setup information. Engineers and technicians deploying IVI drivers in automated test environments would install this package first to establish the required common services, after which individual IVI instrument drivers and the applications that call them can operate correctly on top of the shared foundation provided by the IVI Foundation's components.
