When silicon chips are fabricated, defects in materials (e.g., silicon) and manufacturing errors can result in defective circuits. A very common defect is for one signal wire to get "broken" and always register a logical 1. This is often called a "stuck-at-1" fault. When you list instructions, assume instructions are only of the following types: loads, stores, arithmetic (R-type), arithmetic with immediate(I-type), and branches.
(a) Which instructions fail to operate correctly if the MemToReg wire is stuck at 1?
(b) Which instructions fail to operate correctly if the ALUSrc wire is stuck at 1?
