What features are you looking for that you need PCI.  Do you think it just sounds cool so you are recommending it?   Have you given any thought as to how you plan to interface to the hardware that performs your CPU core functions?  Have you attempted to write ANY kind of system level document that defines this?  Maybe these free cores don't support the features you need to do the interface you are proposing.   Did you notice, no DMA yet, only 32bits ....  Start by defining your requirements, then we can worry about the implementation. Remember, the implementation may have already been for us if you could tell us what it is you need in a prototyping card.

If we do use PCI, we will be forced to use PCBs for the implementation.  We will be forced into a PCB package that interfaces with some type of simulator for doing the layout. I'm not against using PCI if you could tell me why you need it.
