Look-Ahead Carry - Multisim Live Online Circuit Simulator The circuit is a lookahead carry generator which is used for avoiding the long propagation delay associated with carry ripple. This circuit is used for a reasonable width of the addends. As the addends get wider the circuit gets increasingly larger and will also operate slower. A2..A0 and B2..B0 are the addends and Cin is the carry input.
