Consider the following hardware, built exactly as described. Determine a test vector that that tests for a SA-0 fault at node B and propagates the fault to the register C. In that test vector A[1] should be 0. Write your answer as a 3-digit string. E.g. if the answer is A[2]=1, A[1]=1, A[0]=x, then write 11x without any spaces or quotes.

reg [2:0] A;

reg B, C, D;

always@(*)

begin

B = A[2] | A[1];

D = A [1] ^ A[0];

End

always@(posedge clock)

C = B & D;
