Warning(24076): PLL instance "iopll_0|tennm_ph2_iopll" is configured with parameters that differ from the calculated optimal settings - Warning(24076): PLL instance "iopll_0|tennm_ph2_iopll" is configured with parameters that differ from the calculated optimal settings Description Due to a problem in Quartus® Prime Pro Edition software version 26.1 and earlier, when compiling a design with IOPLL FPGA IP targeting an Agilex® 5 FPGA E-Series in speed grade -6, you may see this warning, with a suggestion to change the PLL settings that would result in a VCO frequency that is greater than what is supported by the target device speed grade. For example, the compiler may suggest settings that result in a VCO frequency of 3000 MHz, but the maximum supported VCO frequency in that speed grade is 2400 MHz. Resolution You may ignore this warning when targeting an Agilex® 5 FPGA E-Series in speed grade -6. This issue will be fixed in a future version of the Quartus® Prime Pro Edition software.
