Before running the AI Engine graph simulation, you need test vectors to provide input. Scripts are also provided to compare with AI Engine simulator output for verification. To generate the vectors, run the following command:
$ make gen_vectors
This tutorial includes test vectors, so this step is not necessary before AI Engine simulation. If desired, you can run the matlab/genvectors_softmax_aie_ml_bfloat16.m function from the MATLAB environment to generate test vectors. This function accepts input arguments specifying the number of softmax classes and the number of softmax vectors to generate. This function also creates a file aie-ml/src/config.h, which configures the AIE kernel and simulation to process the generated test vectors.
