    For example, I am using a 30,000 gate FPGA that contains a PCI core design
which ensures that
it is "PCI compliant".
The compliance comes from the fact that the design is supposed to adhere to the
PCI protocol and
all signals meet the stringent PCI requirements when interfaced to the bus. The
vendors have a checklist
to meet.
The PCI core in essence, will "guide" the interface design when routing the chip
to make sure that all timing
parameters are met. My design is a PCI target only, but it could bus master
easily.
