-Design a 4 Bit Ripple Carry Adder in Verilog using 4 full adders

-Please Include test bench and please use a FOR-LOOP when doing "initial begin "

-Include wave simulation if possible as well, thank you

The 4-bit ripple carry adder circuit is shown below. a[3] b[3] a[1] b[1] a[0]b[0] a[2] b[2] 1 b cout FA cin a a b cout FA cin b cout FA cin cout b cout FA cin cin sum sum sum sum sum[3] sum[2] sum[1] sum[0] a[3:0) b[3:0) cout RCA4 cin sum[3:0) Figure 2. The 4-bit ripple carry adder circuit and block diagram You can reuse the full adder design module FA you designed in the Lab2 part 1 for your RCA4 design in this part
