 This command replaces clocked flip-flops with generic $ff cells that use the
 implicit global clock. This is useful for formal verification of designs with
 multiple clocks.
+
+This pass assumes negative hold time for the async FF inputs. For example when
+a reset deasserts with the clock edge, then the FF output will still drive the
+reset value in the next cycle regardless of the data-in value at the time of
+the clock edge.
