For more information on mapper and router methodology, see Mapper/Router Methodology in the AI Engine Tools and Flows User Guide (UG1076).
In general, the methodology for mapping/placing the ADF graph onto the AI Engine-ML array or AIE-ML v2 array remains similar to the AI Engine array. You should keep the updated architecture in mind (new AXI memory access patterns, presence of additional memory tile rows) while constraining the design.
