Why does my Intel® Agilex™ M20K Performance does not meet the specifications in Intel® Agilex™ Device Data Sheet?

Due to a problem in the Intel® Quartus® Prime Pro Edition Software version 21.2, you see that the M20K RAMs in your design do not meet the Fmax performance stated in the Intel® Agilex™ Device Data Sheet.  (Table 32 on page 34)

This problem only affects the following modes in speed grade 4 devices.

The table below shows the performance reported by the datasheet and what is reported in Timing Analyzer.

The problem is in the M20K timing in the Intel® Quartus® Prime Pro Edition Software, the Fmax reported in the Data Sheet is correct.

This problem is fixed starting with the Intel® Quartus® Prime Pro Edition Software version 21.3.
