PCI-SIG^® has enabled PCI Express^® (PCIe^®) technology to be cost-effective and easy to implement by supporting multiple form factors for a variety of applications.

At PCI-SIG, we take pride in ensuring that our specifications operate without a hitch. However, sometimes PCI Express developers need to submit Engineering Change Requests (ECRs) to update parts of the specification so that PCIe integrated products can reach their optimal functionality.
