You can do anything in AHDL like you could in Verilog or VHDL. Just with a lot less typing. But the drawback is it seems to be a dying langage as it is just used by Altera.

Anyway why not just add.

e.g.

in variables

s[2..0] : NODE;

a[1..0] : NODE;

b[1..0] : NODE;

in main section

s[2..0] = (0,a[1..0]) + (0,b[1..0]) ;
