Describe the effect that a single stuck$-$at$-0$ fault $($i$.$e$.,$ regardless of what it should be$,$ the signal is always $0)$ would have for the signals shown below, in the single$-$cycle datapath $($shown in the figure in Part IV$).$ Which instructions $($R$-$type, lw$,$ sw$,$ or beq$),$ if any, will not work correctly? Explain why.

Consider each of the following faults separately:

A$)$ RegWrite $=0$

B$)$ ALUOp$0=0$

C$)$ ALUOpl$=0$

D$)$ Branch $=0$

E$)$ MemRead $=0$

F$)$ MemWrite $=0$
