The AMD Versal™ Network on Chip (NoC) is a high bandwidth interface within a Versal adaptive SoC. It allows high bandwidth and Quality of Service (QoS) support for all resources on a Versal device. NoC is an AXI-interconnecting network used for sharing the data among IP endpoints in the programmable logic (PL), the processing system (PS), and other hard blocks. A single physical NoC channel can be shared by traffic with different latency or bandwidth requirements. The NoC is configured using the NoC compiler to setup the required connections and the QoS. Report power uses the output of the NoC compiler automatically to estimate the power for your NoC configuration. For more information, see Versal Adaptive SoC Programmable Network on Chip and Integrated Memory Controller LogiCORE IP Product Guide (PG313).

xcvp1202. Hence, power is reported only for the used clock buffers in the design. Versal Premium stacked silicon interconnect technology (SSIT) devices support NoC clock gating on for non DFX designs in the present release. Hence, all the clock buffers are used in every design.
Vivado/Vitis generates .xpe file during implementation runs as well as during NoC compiler runs. These .xpe files can be imported to the PDM tool using import functionality for performing detailed what-if analysis. For more information, see Power Design Manager User Guide (UG1556). The generated .xpe file can be found in the following path: project_1.gen/sources_1/common/nsln/NOC_Power.xpe.
