Dear all,
am doing one 4-bit adder,
when i am simulating in hspice, it is not going further.
it was stopping at the line of fourth full adder.
when i have removed the last full adder (with 3-Full Adder and 1-Half Adder), it was working fine.
Please clarify this to me.
here i have added few lines of code as a ref.
