PYNQ: PYTHON PRODUCTIVITY

FPGA GPIO Delay

Hi,

I have one high-speed FPGA board(ZCU104), with a clock 500MHz, output through GPIO, connect with RF cable. So different I/O has a different time delay. I could do timing constraints when synthesizing using Vivado to compensate for the time difference. But as you know, it is not convenient(one time, only set one-time delay parameter, then wait a long time to generate bit file), what I need is to tune the time delay in PYNQ software. Does anyone know if there is one IP I could use? Or I could set it in PYNQ system? Thank you in advance.

Best regards,
Charlie

Can you explain in more detail what you are trying to do?
What IO standard are you trying to use?
This doesn’t seem like a PYNQ question. PYNQ provides Python APIs to control your PL design. If you can do something in a standard Zynq (C/C++) flow to control your IP, then you can also do this with PYNQ.
