Hi, all, I am a beginner in this field.
When I was reading and simulating others' designs, I found many of
them have their input and output registered. They use a Flip flop,
every rising edge of the clock, they have the outputed signal stored
in that flip flip, and then the output of the FF as the final output
of the design.
I am not quite understand why they want the registered signals, it
cause some delay since the final output will wait for the rising edge
of the clock. Is it for synchronization or something else? thanks.
