PCI Express 3.0 Technical Challenges


Correctly routing PCIe 3.0 single traces is a design challenge that few companies can handle well, and taking short cuts in PICMG 1.3 single board computer and backplane designs which utilize the PCI Express 3.0 interface will always result in suboptimal system performance.


For example, with all previous generations of PCI Express it was best practice to keep traces well below 16 inches to insure optimum performance, but the PCIe Gen3 specification makes the length requirement even more restrictive, which is why it’s so important to understand the difference between PCI Express 3.0, 2.0 and 1.1.

The Gen3 specification requires a pre-validation of the link before any data transmission, and if the automatic equalization training cannot establish a reliable link, then it won’t allow the transmission of data at 8Gb/s speeds, resulting in slower than expected card-to-card as well as card-to-SBC data transfers in a typical system design.
