Vitis Networking P4 IP is delivered with the following example designs
contained in the <Vivado_install_area>/data/ip/xilinx/vitis_net_p4_v1_0/example_design/examples
directory:
- Default
- Echo
- FiveTuple
- The table found in this example (BCAM mode) can also be implemented using HBM (see Example Design Use (with HBM BCAM).
- FiveTuple_tinycam
- Forward
- Forward_tinycam
- Calculator
- Advanced Calculator
The Vitis Networking P4 example designs contain the following blocks:
- Control
- Based on the P4 file, determines the IPs in the design and programs any necessary initializations.
- Stimulus
- Takes input from the pcap|user text file, converts it to an .axi file format using C DPI functions, and sends in packets.
- Checker
- Converts the expected packet file to an .axi file format using C DPI functions and checks against expected packets produced by the Behavioral Model.
- DUT Wrapper
- Contains all of the design related modules - e.g. VitisNetP4, HBM, User Externs.
The following figure shows a block diagram of the example design.
