Comprehensive PCI Express 5.0 Architecture Course Details:
MindShare's PCI Express System Architecture course starts with a high-level view of the technology to provide the big-picture context and then drills down into the details for each topic, providing a thorough understanding of the hardware and software protocols.
This course describes additional features added to the architecture when moving from PCIe specification revision 1.1 to 5.0. There is a very large number of features and optional behaviors for PCIe. MindShare will customize this course to cover those features requested by the audience given we cannot cover all topics in the limited training time.
You Will Learn:
- Features of PCIe Gen1, Gen2, Gen3, Gen4, Gen5
- The definition and responsibilities of each of the layers in the interface
- How the hardware-based automatic error detection and correction mechanism works
- The various additional levels of error detection and reporting
- The details of the packet-based protocol used by PCIe
- The address space and packet-routing methods used
- How the various power management techniques work
- The details of the configuration registers that provide control and status visibility to software
- What changes are needed to run the link at 16.0 GT/s (Gen4 speeds) and 32 GT/s (Gen5 speeds)

Who Should Attend?
This in-depth course is hardware oriented, but is designed for both hardware and software engineers. The course contains numerous practical examples of transactions on the link, including relevant analyzer captures of some error conditions. It also covers the rules required for a device to be compliant with the spec. This makes the course ideal for system validation engineers who are evaluating an RTL-level, chip-level, system-level or system board-level design.
