HX2 Xilinx - Spartan-6 / Virtex-6 Integrated PCI Express Block

This course covers the implementation of the Xilinx PCIe block.


Objectives
	An introduction to PCI Express protocol is done at the beginning to be able later to understand the operation of the back-end bus.
	The course details the parameterizing of the PCI Express core.
	User interfaces are deeply detailed.
	Management of errors and interrupts is studied through examples.
	Guidelines to design the user logic are provided.
	The course targets hard PCI Express cores in the Virtex-6 and Spartan-6 FPGAs.
Xilinx software (ISE) is used to synthesize and implement practical examples, Mentor Graphics ModelSim is used for simulation.
A more detailed course description is available on request at info@ac6-training.com


Prerequisites
	Good knowledge of PCIe gen2 protocol, see our course reference IC4
	Good knowledge of VHDL.
	Experience with simulation tools such as Mentor Graphics ModelSim.
	Basic knowledge of Xilinx ISE software.
