Why might the Agilex™ 7 FPGA device fail to configure or reconfigure?

Description

Due to a problem in the Quartus® Prime Pro Edition Software v21.3 and later, Agilex™ 7 FPGA 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 Quartus® Prime Pro Edition Software.
