How to draw a circuit diagram with adders?

[blingbling]

Hi everyone,

Was wondering if someone could help me with on how to draw a circuit that uses a full adder and two half adders and one external gate. Would appreciate the help! Thanks.

Hi,
You need an adder first then you can use it. You can draw it yourself, or you can import it from other circuits. Please either search through this forums or download sample circuit Digital Clock it has some adders.
Please let me know if you need anything else,

I know you can connect one full adder to another full adder. Could I possibly do this ... connect the two half adders together through some gate and then connect it to a full adder? Not sure how that would look like.
