PCI-SIG® Announces Authorized Test Labs Now Available for PCI Express® Technology

Granite River Labs Approved as First Official PCIe® Testing Lab

Granite River Labs (GRL) is thrilled to announce that our facility in Santa Clara, California has been approved by PCI-SIG® to provide Integrators List compliance testing services for PCI Express® (PCIe®) 4.0 Add-in Cards (devices) and Systems (hosts).

We are honored to be the first independent PCIe Authorized Test Lab (ATL) approved by the PCI-SIG to provide “on demand” Integrators List testing. Products that pass rigorous PCIe compliance test requirements at GRL will be listed on the Integrators List, a critical step towards assuring end users that the product is interoperable and backwards compatible with prior generations of PCIe architecture.

In addition to PCIe 4.0 Integrators List compliance, GRL’s comprehensive PCIe specification test services include PCIe 6.0 architecture and earlier electrical and link equalization pre-compliance testing and debugging; IC characterization; and signal integrity validation, simulation and modeling. GRL also offers comprehensive PCIe specification compliance testing and debugging services leveraging Teledyne LeCroy’s test automation solutions, tools, and expertise.
