You Will Learn:

  • PCI Express features and capabilities
  • The definition and responsibilities of each of the layers in the interface
  • Physical Layer changes to support PCIe Gen3, Gen4 and Gen5 such as 128b/130b and Tx Equalization
  • The link training process including changes made in rev 5.0 spec such as Alternate Protocol Negotiation
  • The purpose of equalization and how it is done in PCIe 3.0 and later
  • Features added to Rev 4.0 and Rev 5.0 spec such as Lane Margining, Retimers, System Firmware Intermediary

If you already understand PCIe protocol as described in the rev 2.0 specification and you need to understand spec additions from spec rev 3.0 onwards, this is the course to take. To serve as a refresher, the course starts with a high-level view of the design to provide the big-picture context. The course then drills down into design updates associated with Gen3, Gen4 and Gen5. We cover topics such as 128b/130b, Retimers, Lane Margining etc.

Who Should View?

This course is hardware-oriented, but is suitable for both hardware and software engineers because the configuration registers used to control the hardware are covered in detail. The course is ideal for RTL-, chip-, system- or system board-level design engineers who need a broad understanding of PCI Express. Because the course contains practical examples of transactions on the various bus interfaces, the course is also suitable for chip-level and board-level validation engineers.
