a$.$ Determine if e$/1$ can be propagated to primary output Z$.$ Give justification to your answer using time frame expansion.

b$.$ Convert the design into full$-$scan design using Muxed$-$D scan cell.

c$.$ Based on the full$-$scan design, determine the test pattern to detect e$/1.$ Show the analysis and determine the number of clock cycle required to detect the fault.
