Due to a problem in the Intel® Quartus® Prime Pro Edition Software versions 21.3 and 21.4, designs containing the F-Tile JESD204C Intel® FPGA IP using Intel® Agilex™ 7 devices will fail to pass the Intel® Quartus® Prime Pro Edition Software “Support Logic Generation” phase.
This error is encountered when the selected data rate is not divisible by 64.
To work around this problem, choose a data rate in the JESD204C IP which is divisible by 64.
If this is not practical, then you must select a System PLL output frequency using the following equation:
System PLL output frequency = (Data rate/32) * 2
The resultant System PLL output frequency must be less than or equal to 1 GHz per the System PLL specification.
This problem is scheduled to be fixed in a future release of the Intel® Quartus® Prime Pro Edition Software.
