1. By using Synchronizers u can achieve that.( Synchronizer(2or 3
level is back to back DFFs)
2. If you use if ..else it will give priority encoder style will be
inferred.
where as if you use case statement. balanced logic mux will be
inferred. (CASE statement is the preferred style)
3. Latches will be inferred if you dont use default in case statement.
( Latch remembers the previous clk period value)
