电梯控制器

一、实验题目

以交大一附院住院大楼为例设计一款电梯控制器，能够适用于该大楼所有电梯。（交大一附院住院大楼地下2层，地上20层，共有8部电梯，1号梯停奇数层，2~4号梯停10层以下，5~7号梯停10层以上，8号梯停偶数层。）

二、实验目的

1）掌握verilog语言对组合逻辑的描述；

2）学习testbench的设计方法

3）掌握仿真器（modelsim/verilog/VCS）的仿真、调试、波形输出等常用技巧；

4）掌握DC约束规划方法、综合器使用、结果查看、后仿真等； 5）熟悉简单芯片从规划到实现方法。

三、实验内容

3.1电梯内部以及外部按钮的输出。

3.2设计一个电梯类型控制器模块，使其控制电梯既能奇数层停，也能偶数

层停，也能10层之上，也能10层之下。这里主要使用了组合逻辑电路，通过组合电路来控制输出信号。

3.3分频器模块，这里主控模块使用了1HZ的时钟信号，所以，我们需要使用分频器来产生一个1HZ的时钟信号，1HZ的时钟信号主要用来控制电梯状态的转化，包括上升一层，下降一层，暂停，开门，关门，待命。

3.4主控模块，这里是电梯控制的核心模块，主要实现的电梯上下楼层的判断。

3.5显示模块，显示出电梯在运动过程中当前所在的楼层，使用了动态扫描。

4．2Modelsim前仿真结果

4.2.1

此时，电梯外部有19层和20层的向下请求，13层的向上请求，以及电梯内部的5层的请求，由于电梯类型为ODD，所以20层的向下请求被屏蔽。根据设计规则，电梯会运行到5层后，开门5S，然后关门，并且动态输出电梯层数05。

图6仿真1

4.2.2

电梯停在五层，外部有19层和118层的向下请求，8层的向上请求，电梯内部我请求，因为此时电梯类型为UP10所以8层的想上请求被屏蔽，同时电梯停在五层之前的动作是向上的，所以，电梯先响应19层的向下请求。到达19层后，电梯开门5S，然后关门。运动过程中，数码管动态显示楼层

图7 仿真2

4.2.3

电梯停在19层，此时，外部有20层、12层、4层的向下请求，14层和8层的向上请求，以及电梯内部6层和15的请求。因为此时的电梯类型为BLOW10所以，20层、12层向下请求，14层向上请求，电梯内部15层请求被屏蔽，同时电梯停在19层之前的动作是向下的，所以，电梯先响应内部6层的请求。到达6层后，电梯开门5s，然后关门。运动过程中，数码管动态显示楼层

图8 仿真3

4.2.3

电梯停在6层，此时只有2层和一层的向下请求，所以响应2层的向下请求，到达2层后，开门5S，然后关门。然后有1层的电梯内部请求，电梯回到1层后，电梯内外均没有1任何按键请求，电梯处于WAIT状态，电梯门处于关闭态。

五、实验结论

本次EDA实验使我对整个设计流程有了基本的认识，从代码设计，功能设计，以及后面的功能仿真，代码覆盖率查看，和DC综合约束，生成时序报告的查看，错误的修改，以及最后的后仿真部分，查看最长数据延时，都有了基本的了解。对一些TCL命令也有了初步的认知。

但是，此次设计中不足之处很多，首先是功能方面，没有实现对电梯运动的电机控制，没有加入对电梯门控的信号，自身设计水平还有待提高，代码风格很差，任重而道远。

在DC综合这块，存在很大的问题，很多约束不会添加，违例报告不会修改，还是需要长期的学习才能掌握！
