PCI-SIG Compliance Workshops host interoperability and compliance tests. Interoperability tests enable members to test their products against other members’ products. Compliance tests allow for product testing against PCI-SIG test modules.

Both testing types issue “pass” or “fail” results for each test area examined. To formally label products as compliant, they must score a minimum of 80 percent on interoperability tests and pass all required compliance tests.

Tested Specifications
Interoperability and compliance tests focus on the latest PCI specifications, specifically:

• PCI Express 5.0
• PCI Express 4.0
• PCI Express U.2®/SFF-8639/ (8 GT/s)
• PCI Express M.2™ (PCIe M.2) (8 GT/s) (Preliminary FYI Only)​

Test Areas
PCI Express compliance testing includes:

• Electrical Testing - Examines platform and add-in card Transmitter and Receiver characteristics
• Configuration Testing - Examines configuration space in PCIe devices
• Link Protocol Testing - Examines device’s link-level protocol behavior
• Transaction Protocol Testing - Examines devices transaction-level protocol behavior

Corresponding Test Guides by specification version can be downloaded here. These downloadable guides include test descriptions, test specifications, procedural guidelines and required tools.

Authorized Test Lab Program
The PCI-SIG has announced an Authorized Test Lab Program for PCIe 4.0 devices. This program is in addition to the normally scheduled PCI-SIG Compliance Workshops held periodically throughout the year. This Authorized Test Lab program will serve the same goal by replicating testing at a Compliance Workshop using the same PCI-SIG approved and MOI listed test equipment to ensure compliance against the PCI-SIG specifications. Initially the PCI-SIG is working with Granite River Labs as the first PCIe Authorized Test Lab to provide PCIe 4.0 Compliance Testing for PCI-SIG members..More information about the program and information for registering products for testing can be found at: https://pcisig.com/developers/authorized-test-lab-program.
