Hello everybody,
I'm a little bit confused about the difference of reset and enable in digital IC...
for a design point of view, the enable signal helps to prevent glitches at the output port, so by enabling the circuit only when the data inputs are ready the output hasn't got any of it.
the reset signal instead initialize every registers, fsm etc to its start point.
am i right? if yes, i'm thinking that for a simple fsm, are both the signals present?
if yes what's the meaning of enable in a single fsm? a moore fsm reacts only at every clock edge so enable isn't very meaningfull; or i'm just missing some concept that i'm not so good to find by googling.
Thank you so much
