Figure 5–37 shows all the signals of a full-featured IP Compiler for PCI Express
available in the Qsys design flow. Your parameterization may not include some of the
ports. The Avalon-MM signals are shown on the left side of this figure.
1 The IP Compiler for PCI Express available in the Qsys design flow does not support
the use of an external PHY.
