[pci] PCI bridge as Guest

["Radwin Zagala" <rzagala@softhome.net>]

Good day guys!

I'd like to ask and clarify some things about the pci bridge core. My
question has something to do with the wishbone interface which I'm not
familiar with, so any help is greatly appreciated.

If I wanted to implement the core as a guest with the connection of a
wishbone compliant device, which parts of the pci bridge core are used?
Is the wishbone slave module as well as its FIFOs still in use? Since
data is requested from the pci interface to the device side, I was
thinking that data transfers are passing through the pci target module
then to the wishbone master module, then eventually to the wishbone
compliant device. In this case, what is the role of the wishbone slave
module that is connected to pci master module? I might be
misunderstanding the operation of the core so please correct me if I'm
wrong.

Thank you very much for any help!

Regards,
Radwin Zagala
