- 高楼电梯自动控制系统(Windows平台上运行的ispLEVER编程软件。 ): 1统控制的电梯往返于1-9层楼。 2客要去的楼层数可手动输入并显示（设为A数）。 3梯运行的楼层数可自动显示（设为B数）。 4A>B时，系统能输出使三相电机正转的时序信号，使电梯上升； 当A<B时，系统能输出使三相电机反转的时序信号，使电梯下降； 当A=B时，系统能输出使三相电机停机的信号，使电梯停止运行并开门； 5是上升还是下降各层电梯门外应有指示，各层电梯门外应有使电
PN4
- 语言：VHDL 功能：该PN4序列的特点为将一个4位序列的前两位取异或，再让序列左移一位，用异或的结果作为序列的最后一位。序列周期是15，即15位伪随机序列。其中包括序列的产生模块和检测模块。对于误码检测，首先捕获相位。然后，规定测试的码的总个数，统计这些码中有多少个不能满足PN序列特点的，用计数器统计个数。如果发现误码过多，可能是相位失调，重新捕获相位，再进行误码检测。 仿真工具：modelsim 综合工具：quartus -Language: VHDL function:
