Why does ASx4 configuration fail for Intel® Stratix® 10 devices when using OSC_CLK_1 as the configuration clock source?


Due to a known problem in Intel® Quartus® Prime Pro Edition software version 20.2 and later, ASx4 configuration of Intel® Stratix® 10 devices may fail intermittently when the below clocking combinations are used.

AS_CLK is 100MHz and OSC_CLK_1 is 125MHz

AS_CLK is 125Mhz and OSC_CLK_1 is 25MHz

AS_CLK is 133MHz and OSC_CLK_1 is 25MHz

All other combinations are not impacted.



As a workaround, avoid the frequency combinations stated in the Description.

This problem will be fixed in future version of Intel® Quartus® Prime Pro Edition software.
