Problem 1: Ripple-Carry Adder Design

Design, simulate and verify a 16-bit ripple-carry adder by performing the following additions/subtractions (the values of a and b are given in decimal):

(i) (-10) + (100),

(ii) (63) - (- 127),

(iii) (15) + (95),

(iv) (-32) + (79),

(v) (-59) + (-16),

(vi) (1000) + (2001),

(vii) (-3210) + (15).
