User Guide
The Cyclone V Hard IP for PCI Express offers exactly the same feature set in both the
MegaWizard and Qsys design flows. Consequently, your choice of design flow
depends on whether you want to integrate the Cyclone V Hard IP for PCI Express
using RTL instantiation or using Qsys, which is a system integration tool available in
the Quartus II software.
f For more information about Qsys, refer to System Design with Qsys in the Quartus II
Handbook.
h For more information about the Qsys GUI, refer to About Qsys in Quartus II Help.
Figure 2–2 illustrates the steps necessary to customize the Cyclone V Hard IP for PCI
Express and run the example design.
