![]() ![]() All input values for a and b are positive and must be within the permissible range for 4-bit unsigned numbers. ![]() ![]() In addition, you must modify the supplied test bench file (add six tbv) so that it produces the appropriate inputs and outputs to test the 4-bit adder/subtractor. You will need to modify the code so that it becomes a4-bit adder, then add the necessary logicto implement the subtractor. Lab Assignment: Using a text editor, modify the supplied Verilog file for the 6-bit adder (add six v) so that it implements the 4-bit adder/subtractor shown in Figure 3. instantiations of the 1-bit full adder module: the labels you place on the circuit diagram in Figure 2 must correspond to the variable names as used in the Verilog file. Pre-lab Assignment On a copy of the circuit diagram given in Figure 2, label all the variables declared in the supplied Verilog file for the 6-bit adder (add six. Verilog HDL is a general-purpose hardware description language that is similar syntax to the C programming language. Half Adder and Full Adder (Dataflow Modeling) Half Adder (Dataflow Modeling): module halfadder( input a, input b, output sum, output carry ) ass. Taking the 2's Complement of the number to be subtracted enables the use of the same basic circuitry for both addition and subtraction. Circuit Diagram for 4-bit Asynchronous up counter using JK-FF : Verilog Code for jkff: (Behavioural model) module jkf. Transcribed image text: EECE 144 Lab #6: 4-bit Adder/subtractor in Verilog Introduction: A full adder circuit may be converted to an adder/subtractor with the addition of a few gates. ![]()
