LogiCORE PCI - Does the PCI Interface support multifunction capability?

Description

General Description:

Does the LogiCORE PCI interface support a multifunction capability?

Solution

A multifunction device is a single piece of silicon that incorporates between two and eight functions. The multiple functions within a device share the device's PCI interface.

The BIT 7 in the Header Type register in the PCI configuration space is used to determine whether or not a device has multifunction capability. The Xilinx LogiCORE PCI interface does not support multifunction capability and has this read-only bit set to zero.
