HRR-10101: Asynchronous Clears

Asynchronous clear signals always prevent the Intel® Quartus® Prime Pro Edition software from retiming paths in designs using the Intel® Hyperflex™ architecture, limiting the speed at which the designs can be operated.

Recommendation

Remove asynchronous clear if the circuit naturally resets when the reset is held long enough to reach a steady-state equivalent of a full reset.
