Prior to running the AI Engine graph simulation, test vectors are required 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
Test vectors are included with this tutorial, so this step is not strictly necessary prior to AI Engine simulation. If desired, one may 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 properly process the generated test vectors.
