Error(15360): DSP block WYSIWYG primitive "u0|a10_native_fixed_point_dsp_0|twentynm_mac_component" has unconnected port ACLR[0] -- port must be connected because corresponding register is used

Due to a problem in the Intel® Quartus® Prime Pro Edition Software version 20.3 and later, you may see this error when you are using the Intel® Arria® 10 Native Fixed Point DSP IP. The error happens because the user is enabling registers for "az" and "bz" but not using the "az" and "bz" ports.

To avoid this error, disable the registers for "az" and "bz" in Data "z" Configuration if you are not using "az" and "bz" ports.

This error is planned to be fixed in a future release of the Intel® Quartus® Prime Pro Edition Software.
