Description
Due to a problem in the Intel® Quartus® Prime Pro Edition Software v21.3 and later, Intel Agilex® 7 devices may fail to configure if an unstable clock signal is applied to the System PLL 0 or System PLL 2 during device configuration.
Resolution
To work around this problem, ensure that used F-Tile System PLL 0 and System PLL 2 reference clock signals in your design are correct and stable before the device configuration begins.
This problem is scheduled to be fixed in a future release of the Intel® Quartus® Prime Pro Edition Software.
