这学期上了电子系的第一门核心课程ELEC151——数字设计（Digital
Design）。讲的内容挺难的，而更让我们每个人头疼的就是实验课（Lab
Session）。
明天（确切的说是今天）下午要做的实验是用OrCAD
Rel.
9.1绘制四位加法器的电路图，19页的实验手册，加上2页的实验报告，我几乎是熬了个通宵才做完。
下面这幅图就是我最终绘制完成并调试成功的电路图：
而这只是我学习电子与计算机工程学的开始，以后还有更难更复杂的电路要设计，今年我还加入了机器人比赛队（Robocon），如果幸运的话，我们可以打败港大和中大，代表香港赴印度参加亚洲区的决赛！

（此电路图的EDA
Netlist，够复杂吧！）
