MOD2 can be constructed structurally using the MOD1 circuit as shown below: MOD1 MOD2 Y3 g Y2 MOD1 Y2 Y1 Q2.3 5 Points Write a testbench to test MOD2 using the following four input patterns Here, we have B1 of the right-most MOD1 connected to 1,82 of the same is connected to 81 of the second MOD1 from the right, and so on, until the left-most MOD1, in which its B2 is taken as the B output for MOD2. Write a structural Verilog module to model MOD2 that instantiates four instances of MOD1 and connects them as indicated above. 1 MOD11 Y1 78% Done 11:31 PM Fri 6 Oct Submit Verilog Assignment #1 _ Gradescope.pdf + IKE 6 of 6 Save Answer Q2.3 5 Points Write a te atest bench to test MODZ using the following four input patterns X4 X3 X2 X1 0000 0001 0 110 1 100 Save Answer Q2.4 5 Points Please select file Select file) Save Answer www Simulate your test bench and attach a snapshot of the generated waveform using the button below. Q2.5 1 Point Save Answer A Save All Answers What do you observe about the input/output relationship of Circuit MOD2? Hint: Consider X-X4, X3, X2, X1 as the bits of an unsigned 4-bit binary integer where X4 is the most significant bit (MSB), and Y-Y4, Y3, V2, Y1 as the bits of an unsigned 4-bit binary integer where Y4 is the MSB. OMOD2 increments X by 1, and 8 is the final carryout bit OMOD2 decrements X by 1, and B is the final borrow bit OMOD2 counts the number of 1s in X and B indicates if X has any Os or not OMODZ counts the number of Os in X, and B indicates if X has any 1s or not Q Submit & View Submission> 78% Done
