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.

The PCI-SIG Serial Enabling Workgroup (called the “SEG” for short) is the PCI-SIG workgroup charged with running the PCI Express^® (PCIe^®) compliance program.

I’m pleased to share that PCI-SIG has released the PCIe 4.0 Specification Version 1.0 and it is now available for download on our website.
