Due to a problem in the Intel® Quartus® Prime Pro Edition Software v21.2, the F-Tile Ethernet Intel® FPGA Hard IP design example fails to pass the “Support Logic Generation” phase in the Intel Quartus Prime Software.
The following error message occurs when using the 10GE-1 with PTP-enabled variant and a custom system phase-locked loop (PLL) frequency such as 903.125 MHz:
“Error (21842): Solver failed to find a solution”
To work around this problem in the Intel® Quartus® Prime Pro Edition Software v21.2, choose the default system PLL frequency of 805.664062 MHz when using the 10GE-1 with PTP variant.
This problem is fixed starting with the Intel® Quartus® Prime Pro Edition Software version 22.1.
