We used 3 files with each lab project in Vivado. What do we call the file that associates variables with actual pins on the FPGA? What file has code that can be used to verify that the design is working as it should be before we generate the bit file to program the board? H. Take the 1 bit full adder module and instantiate it 4 times in a larger module to make a 4 bit adder. All you have to do is fill in the instantiations is the 4 bit module. Solution G.Constraint file (-constrset)) testbench H. Full_Add FA0(Sum[0],Ripple_Carry[1],A[0],B[0],Carry_In); Full_Add FA1(Sum[1],Ripple_Carry[2],A[1],B[1],Ripple_Carry[1]); Full_Add FA1(Sum[2],Ripple_Carry[3],A[2],B[2],Ripple_Carry[2]); Full_Add FA1(Sum[3]Carry_Out,A[3],B[3],Ripple_Carry[3]);.
