Write the Verilog code for a two-input, two-bit adder. The inputs are to be set by switches SW0-SW3 the three-bit result is to be displayed on LED0-2. Then write the Verilog code to add two hexadecimal integers stored in 4 bits each. The result should be placed in two hex integers of four bits each. The inputs should be set by SW0-3 and SW4-7. The inputs and the result should display on the four 7-segment displays. The right two displays will be the two addends and the left two displays will be the two hex representations of the sum. A simple google search will give you the Verilog for a 7-segment display decoder. NOTE: the DE0 display is 'on' if the input is 0 and 'o' if the input is 1. This may require you to modify the output of the 7-segment decode module.
