SoC Debug I/O

The AMD Versal™ adaptive SoC includes device-level debug and trace capabilities. The debug hardware features include the following.

  • Four host debugger access points to the DPC:
    • PCIe® Host: high-speed, high-bandwidth debug protocol
    • Aurora host: high-speed, serial debug protocol path to DPC
    • PL interface: high-speed, high-bandwidth streaming
    • JTAG
  • Debug environment for the following:
    • PS RPU and APU processors
    • PMC and PSM processors
    • PL, CPM, and AI Engine
  • Intrusive and non-intrusive debug
  • Interfacing to ChipScope™
  • Daisy-chaining of multiple devices for debug or configuration through a unified cable
