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.

PCI Express (PCIe^®) has been widely adopted in a number of applications that range from small, power-constrained IoT sensors and mobile devices to servers and networking and communications equipment.
