how to write a VHDL code for a full-adder (FA) using 2 half-adders and an OR gate

 

homework?

 

yeah it's homework like prelab.I was unable to link that

You need to show YOUR best effort to work YOUR homework problem. We can then see what approach you are taking, what you are doing right, and where you are going astray. That will help us help you.

 

Do you know how to make a full adder from gates?

Do you know how to describe those connections in VHDL?

 

yes ı know how to write vhdl code and connect the starter board but ı cant related to XOR gate and OR gate .ı'm a little bit confused.

...and do you know how to make a full adder from gates?

If not, write out a truth table, you can always start there.

Edit: After realizing you have to use half adders, do you know how to connect them to form a full adder?

 

Where is the XOR gate coming into this -- you are asked to use two half-adders and an OR gate to make a full adder.

So it sounds like you need to look up what a half adder is and what a full adder is and how you can use half adders to make full adders.

 

Thank u 4 your helping guys ı wrote this code.
