*Q1:

題目有兩個小錯誤：
1. V. Example 中, figure 2. 應該有 4 條 paths 而不是3條 (p.3)

2. V.Example 中的下列敘述 (p.4)

   Because setting signal b to ‘1’ will always
   imply a ‘1’ at signal e in the circuit, we can conclude that the requirements of setting b to ‘1’ and e
   to ‘0’ simultaneously for the transition propagation derived above is not possible.

   和 figure 2. 不搭，G2 和 a 的接線應該要換成G2 和 b 的接線


*A1:

錯誤已修正，請重新下載題目


*Q2: (5/31, 2002)

如果在比較path長度時，發現不止一條一樣
那output時候  應該以什麼條件來決定先後順序

*A2:

   Critical paths of the same length can be ordered randomly.
