Hi,
I need a verilog code for 16bit signed carry look ahead adder,
Please help me.
 

The easiest way to get the code will be to write the code yourself.

we will use a module called sum to perform the XOR since the carry is computed seprately

module sum(a,b,carryin,result);
input a,b,carryin;/*add these bits*/
output result;/*sum*/

assign result=a^b^carrin;
/*compute the sum*/
end module
