The NoC Debug Answer Record provides a good introduction to debugging the NoC using the NoC Peripheral Interconnect (NPI) registers. This process uses internal NoC registers, which are described in Versal Adaptive SoC Register Reference (AM012) and Versal Adaptive SoC NoC and Integrated Memory Controller NPI Register Reference (AM019) to help pinpoint problems.
You can use the following command can be used to determine the base NPI Base Address for NoC modules in the design.
report_npi_addresses -of_objects [get_sites -filter {IS_USED && SITE_TYPE =~ "NOC_*"} ]
