Example Design
The Altera PHYLite for Parallel Interfaces IP core is able to generate an example design that matches the
same configuration chosen for the IP. The example design is a simple design that does not target any
specific application; however you can use the example design as a reference on how to instantiate the IP
core and what behavior to expect in a simulation.
Note: The .qsys files are for internal use during example design generation only. You should not edit the
files.
