If i have p0,p1,p2.......p15 as separate 1 bit outputs,thencan i make a 16 bit bus [15:0] using all these individua outputs???
I m making a 8*8 wallace multiplier and i want to combine all these 1 bit outputs to make a 16 bit output.how to do that???
 

Yes, you can just define a suitable signal for this purpose. In VHDL, you could use something like this:
Code: 
signal p : std_logic_vector(15 downto 0);

...

p(0) <= p0;
p(1) <= p1;
...
p(15) <= p15;
 
Why are they all separate in the first place?
 

because if i take them as a bus and write my code...it shows me warning for each product term...
