This lab describes the process of generating an AMD Versalâ„¢ device QDMA design containing 4 PFs, 252 VFs and AXI4 Memory Mapped interface connected to the network on chip (NoC) IP and DDR memory. This design has the following configurations:

  • AXI4 memory mapped (AXI MM) connected to DDR through the NoC IP
  • Gen3 x 16
  • 4 physical functions (PFs) and 252 virtual functions (VFs) with Mailbox connections.
  • MSI-X interrupts
This lab provides step by step instructions to configure a Control, Interfaces and Processing System (CIPS) QDMA design and network on chip (NoC) IP. The following figure shows the AXI4 Memory Mapped (AXI-MM) interface to DDR using the NoC IP. At the end of this lab, you can synthesize and implement the design, and generate a Programmable Device Image (PDI) file. The PDI file is used to program the Versal device and run data traffic on a system. For the AXI-MM interface host to chip (H2C) transfers, data is read from Host and sent to DDR memory. For chip to host (C2H) transfers, data is read from DDR memory and written to host.

This lab targets a xcvc1902-vsvd1760-1LP-e-S-es1 part on a VCK5000 board. This lab connects to DDR memory found outside the Versal device. For more information, see QDMA AXI MM Interface to NoC and DDR with Mailbox.
