Well, I know it. In our team we've dealed with PCI and PCI-e from both
sides - at PC level and at FPGA level.

However for didactic purposes it is good sometimes to let students to
work with hardware, which is directly coupled to the CPU bus
(like EBI in ARMs) before they start to deal with more complex
buses like PCI.
