Question

Design and Test an 8-bit Adder using 4-bit adder. Use

4-bit adder coded in class using full adder that is coded using data flow model. Use test bench

to test 8-bit adder and consider at least five different test vectors to test it.

Answer #1

hi,

i hope you want design and testbench in verilog,

if you want in other please dont give negative review(write in comment)

so this is 1 bit addr design

after that i did instatiation of 1_bit_addr and make 4 bit addr..

after that using 4_bit_addr i did make 8_bit_addr

this is testbench code for 8_bit_addr

you can make TB for 4 bit and single bit just change pin a,b,sum [7:0] to [3:0]

another things will be same

command you can see

thanks...
