Error (23527): No route for refclk connection from "<Refclk ibuf name>" to "<IOPLL name>". Promote refclk to a global clock or use a dedicated IOPLL refclk pin. - Error (23527): No route for refclk connection from "<Refclk ibuf name>" to "<IOPLL name>". Promote refclk to a global clock or use a dedicated IOPLL refclk pin. Description You might see this error in the Quartus® Prime Pro Edition Software when you use a GPIO pin as a reference clock for an IOPLL FPGA IP on Agilex™ 7 device. Resolution To avoid this error, follow the steps below: Use this GPIO pin as an input clock for a Clock Bridge IP and use the Clock Bridge IP’s output clock as the reference clock for the IOPLL FPGA IP. Set this GPIO input signal as a “global signal” in the Assignment Editor.
