Error(22507): The active serial clock AS_FREQ_100MHZ is not supported in device initialization clock INIT_INTOSC.

Description

Due to a problem in the Quartus® Prime Pro Edition Software version 23.3 and earlier, you might see this error when changing the Configuration clock source from OSC_CLK_1 pin to Internal Oscillator in the Device and Pin Options.

This error is caused by an incorrect .qsf (Quartus Settings File) assignment.
 

Resolution

To work around this problem, replace the .qsf assignment:

set_global_assignment -name ACTIVE_SERIAL_CLOCK AS_FREQ_100MHZ

with:

set_global_assignment -name ACTIVE_SERIAL_CLOCK AS_FREQ_115MHZ_IOSC
