I have a design with a Cyclone10 LP that needs to talk to a RGMII PHY, which expects a clock signal.
I use a PLL to generate a 125 MHz clock, and would now like to route that to an output pin which is PLL4_CLKOUTp.
The fitter returns me the following warning:
Warning (15064): PLL "PLL_Cy10LP:PLL_inst|altpll:altpll_component|PLL_Cy10LP_altpll:auto_generated|pll1" output port clk[3] feeds output pin "SC3_ETH0_TX_CLK~output" via non-dedicated routing -- jitter performance depends on switching rate of other design elements. Use PLL dedicated clock outputs to ensure jitter performance
Do you have any idea on how to solve this warning?

Hi Pannet,
If you have connected to Pll output pin to PLL4_CLKOUTp.
You can ignore the warning.
