Challenge
- Open 
CH2/SystemVerilog/build/challenge.xprorCH2/VHDL/build/challenge.xpr. - Modify the lines in 
challenge.svto implement a full adder: 
SystemVerilog
  assign LED[0]  = ; // Write the code for the Sum
  assign LED[1]  = ; // Write the code for the Carry
    VHDL
  LED(0)  = ; -- Write the code for the Sum
  LED(1)  = ; -- Write the code for the Carry
    Modify tb_challenge.sv to test it:
SystemVerilog
    if () then // Modify for checking
    VHDL
    if … begin -- Modify for checking
    Hint: You may want to jump ahead in the book at Chapter 3, Combinational Logic to look at addition or do a quick web search.
