Dave_59 am using XILINX... n the code goes as follows ..
Pls helpme..
module adder(result,operand1,operand2);
input signed [31:0]operand1;
input [15:0]operand2;
output signed [31:0]result;
reg signed [31:0] result;
always @(operand1,operand2)
begin
result = operand2 + operand1;
end
endmodule
I tried the code given.. It is just adding the two giving a negative sign.. Can u pls solve this?? It has been so many days and u people couldn't solve 1 problem!!

It should add or subtract depending upon the sign...
our unsigned number is 16 bits in range (it is nvr never going to have a negative value) while the other number is signed n of 30 bits in length.. we want to add or subtract depending on the sign of the signed number.. Can u please write a code on how to do it?? thanx fr d help :)
actually I on't want the output in the form of 32758 for -10 as output , I want it as -10 if I have done 20-30. How to implement this??
thanx fr ur responses.. plz hlp me solve this problms. I will attach test bench if u want.
I meant I hv to add a signe number with an unsigned..
for example 20 + 10, 20 + (-10), 20 + (-30)
Basically an adder subtractor block where 1 input is signed and the othe unsigned. How do I do it??
