这个项目的设计时为了避免火车事故。在这里我们保持火车引擎驱动程序会忙的操作如吹号角，任何增加 / 减少的速度，灯亮着。驱动程序已经执行任何这些，在一段特定时间内的行动。如果驱动程序不执行的操作，火车本身得到弯下腰。驱动程序的执行行动使他很忙，总是将警报。机警的驱动程序可以减少意外。

Part III Figure 2a shows a circuit for a full adder, which has the inputs a, b, and ci, and produces the outputs s and co. Parts b and c of the figure show a circuit symbol and truth table for the full adder, which produces the two-bit binary sum cos = a + b + ci. Figure 2d shows how four instances of this full adder entity can be used to design a circuit that adds two four-bit numbers. This type of circuit is usually called a ripple-carry adder, because of the way that the carry signals are passed from one full adder to the next. Write VHDL code that implements this circuit, as described below. 2
