Compile and simulate the design to confirm it works as you expect.

[shell]% cd <path-to-design>/aie/ifft4096_2d
[shell]% make clean all
[shell]% vitis_analyzer aiesimulator_output/default.aierun_summary

Inspecting vitis_analyzer, note the resource count of 16 AIE-ML v2 tiles.

Achieved throughput for:

  • Front 64-point IFFT + point-wise twiddle multiplication = 2731 MSPS

  • Back 64-point IFFT = 3436 MSPS
