This section guides you through the steps necessary to customize the Arria Hard IP
for PCI Express and run the example testbench in Qsys. Reviewing the Qsys Example
Design for PCIe
For this example, copy the Gen1 x4 Endpoint example design from installation
directory: <install_dir>/ip/altera/altera_pcie/altera_pcie_hip_ast_ed/example_design
/
<device> directory to a working directory.
The following figure illustrates this Qsys system.
The example design includes the following four components:
■ DUT—This is Gen1 x4 Endpoint. For your own design, you can select the data
rate, number of lanes, and either Endpoint or Root Port mode.
■ APPS—This Root Port BFM configures the DUT and drives read and write TLPs to
test DUT functionality. An Endpoint BFM is available if your PCI Express design
implements a Root Port.
