Abstract

Disclosed is a device which allows the testing of small form factor PCI Peripheral Component Interconnect cards in a standard form factor PCI slot. In a standard PCI slot, the small form factor PCI card may be tested utilizing existing PC software, thus removing the need to create additional test software for in-situ testing.

Stand Alone Test Methodology for the Small Form Factor PCI Cards

Disclosed is a device which allows the testing of small form factor PCI ( Peripheral Component Interconnect ) cards in a standard form factor PCI slot. In a standard PCI slot, the small form factor PCI card may be tested utilizing existing PC software, thus removing the need to create additional test software for in-situ testing.

There are a three small form factor PCI card industry standards; Compact PCI, Mini PCI and PCI Mezzanine Card (PMC). The device is a special PCI adapter which translates the small form factor PCI card connector into a standard PCI card connector so that the small card can be tested outside of the system for which it was designed. This special PCI adapter card is a passive device that will include connectors to accept the small form factor cards. It can have only one kind, or all three standards mating connectors. A carefully designed card must be done to ensure compliance with the PCI's electrical specifications.

The advantages of this are twofold, first, the small form factor card is often a redesign of an existing PCI card and the test code written for that PCI card (DOS diagnostics for example) can be utilized without having to write special diagnostics to run in the small form factor platform. In many cases, the small form factor system will not be able to run a standard operating system for which the diagnostics already exist and additional development resource will be...
