Hi Jerry,

there are ways to do this but I'd like to recommend that you don't use these. Think again and again if you can avoid combinational delays. The delay depends on the current routing and therefore changes from compilation run to compilation run. Maybe you can describe what you needs to do an the forum users can propose alternate solutions?
