The AIE to HDL block connects the output of AI Engine block with the input of HDL block. This block accepts variable size signal from AI Engine blocks along with the tready signal which indicates whether the HDL domain can accept the data. This block inherits the input data type from the input signal.

Note: If the HDL domain tready signal stays low for a long time, eventually the internal buffers in the AIE to HDL block overflow and the simulation stops. The bit width of the tdata output of the AIE to HDL block is limited to 32, 64, and 128 according to hardware functionality.
