Why is the maximum number of I/O PLLs incorrectly reported in the Total PLLs Fitter Summary report?

Description

Due to a problem in the Quartus® Prime Pro Edition Software version 25.1.1 and earlier, you might see that the maximum number of I/O PLLs for Agilex® 5 FPGA devices is stated incorrectly in the Total PLLs Fitter Summary report.

Resolution

The compilation will pass as long as the number of I/O PLLs used in the design does not exceed the actual maximum number of I/O PLLs supported by the specific device. The correct maximum number of I/O PLLs supported can be checked from the PDF with the title of Agilex 5 FPGAs and SoCs <Series> Product Table.

This problem is fixed beginning with the Quartus® Prime Pro Edition Software version 25.3.
