Vitis™ software platform generates an .xpe file that can be imported to provide an accurate starting point for AI Engine power estimation. Once imported, all the configuration is generated and power can be estimated more accurately compared to the manual entry mode. The .xpe file generated by the Vitis™ software platform (in Work/reports directory), when imported, averages out Vector Load and Memory R/W rate for a particular kernel type. For example, all the cores of kernel type INT8 vector load and the R/W rate is averaged and populated in a single row of XPE. The Interconnect Load is not a default of 12% in the import flow. Instead, it is computed by the tool based on the stream usage for each AI Engine tile.
Note: You can import the .xpe file to the AI Engine sheet using the Import button at the top.
