Thank you for the link.I am having this table.Here it is given for A and B only.My question is for adding 4 times..as if I am taking the s1 range (8 downto 0) as per table.It is showing error which I have posted above.

When I an going for s1 range (10 downto 0 ) it is working fine.So my question is how to decide this range if I want to add multiple times.
