HRR-10203: Register Power-Up Settings Conflict with Device Settings

Recommendation

Violations of this rule identify register names with initial values dropped. When the DISABLE_REGISTER_POWER_UP_INITIALIZATION power-up setting is ON, register initial conditions become undefined on the device. This condition reduces bitstream size at the expense of globally dropping initial register values.

Confirm functional correctness of dropping initial register values. Next, assign the setting IGNORE_REGISTER_POWER_UP_INITIALIZATION ON to registers or their hierarchy to waive those initial values.
