各位同學大家好：
相信大家在看助教所提供的hw3.pdf時，在作業要求的部分應該有看到下列內容：
2. Report (30%) You should also introduce and discuss about your design.
Following are some requirements of your report.
Circuit diagram (15%)
Plot the circuit diagram of your design. You are encouraged to plot it
hierarchically so that the reader can understand your design easily.
這裡的＂circuit diagram＂只要畫到邏輯閘等級(gate-level)就可以了，
也就是AND，OR這種邏輯閘就可以了，不需要畫到電晶體(MOS)層級
