digital design using vhdl

in VHDL you can use the ** operator to get x^y

like this:

a <= b ** c; where a, b and c are all integer.

But if you want to synthesize it, one of either the B or C values needs to be a constant.

Thank u sir.

One more doubt is any symblols to do logical operations like and or exor like C programming....

greetings sir

a <= b xor c;

but you cant do logic operations on integers, because they are not logic types. you have to do them on std_logic/vector/signed/unsigned.
