求助大神们 一个电路设计的题目

Design a Mealy circuit has two inputs, X and Y, and two outputs, Z and W. If the two inputs are 0 at the previous clock rising-edge and then 1 at the next clock rising-edge, then an output Z = 1 (else Z = 0). If one of the inputs is set to 1 and the other is 0, then a warning light W = 1. W = 0, once X = Y = 0.

时序逻辑，先设计真值表，画出状态图，用电路来实现功能便可以了。
