PYNQ: PYTHON PRODUCTIVITY FOR ZYNQ

What does bindto mean

In [https://pynq.readthedocs.io/en/v2.5/overlay_design_methodology/overlay_tutorial.html]

The section on creating a driver has the line: bindto = [‘xilinx.com:hls:add:1.0’]

What is this line doing?

As stated in the documentation, it binds the driver to a specific hardware IP. So if you have an HLS IP add, that IP will be automatically assigned that driver. You can specify multiple IPs in that list, e.g. https://github.com/Xilinx/PYNQ/blob/master/pynq/lib/video/dma.py#L593
