After compiling your Agilex™ 7 F-Tile device in the Quartus® Prime Pro edition software version 24.2, you may see the following critical warning when using the F-Tile Reference and System PLL Clock IP.

 

Critical Warning(23784): Detected undriven port 'avmm_clk' of system clock IP 'system_pll_ref_i0|systemclk_f_0'. Ensure that the 'avmm_clk' port is driven by an appropriate driver.

 

In the Quartus® Prime Pro Edition Software version 24.2, the F-Tile Reference and System PLL Clock IP avmm_clk and avmm_rst ports are driven internally and disconnected from the top-level IP ports.

Resolution

To work around this problem, you can connect a clock to the avmm_clk port of the F-Tile Reference and System PLL Clock IP. It is also safe to ignore this critical warning.

 

This problem will not be fixed in a future version of the Quartus® Prime Pro Edition Software.
