FPGA程序,使用Verilog语言生成1个脉冲可调的PPS脉冲信号。(FPGA program generates 1 PPS pulse signal, using Verilog language.)

采用Xilinx公司的Spartan6 FPGA设计PCI Express的详细参考资料(Xilinx' s PCI Express, Spartan6 FPGA design, detailed reference information)

数字时钟，包括流程图以及编码和完整的实验报告，内容详细丰富。(Digital clock, including flowcharts, and coding and a full lab report, detailed and rich.)

我用VHDL写的正弦，用FPGA内部ROM，有仿真testbench,在quartus里可以运行。在板子里已经验证-I used to write VHDL sinusoidal, using FPGA internal ROM, has simulation testbench, you can run in Quartus. Yard has already been verified in the plates

When the initial input falls between the Switch off point and Switch on point values, the initial output is the value when the relay is off.

说明：  实现24小时计时，因为位数不够，这里是12进位，可自行调整进位数(Realize 24-hour timing, because the number of digits is not enough, here is 12 carry, you can adjust the carry number by yourself.)

具有桥式结构的传感器很多，如利用应变原理、磁电阻原理和其他变电阻原理的传感器，可以实现对压力、位移、加速度、磁场等物理量的测试。这种结构的差分输出可以增加灵敏度，也有一定抵消外加干扰的能力。而且有的虽不是差分输出，比如电阻分压式的输出，可以认为是“半桥”，我们还可以人为的加上另一半，即加上一对精密电阻和一个电位器组成另一个分压电路，形成差分输出。每次调节电位器使差分输出为0，抵消零磁电压。-Bridge structure with many sensors, such as the use of contingency theory, the principle of magneto-resistance and other variable resistance sensor principle can be achieved on the pressure, displacement, acceleration, magnetic field, such as physical tests. The structure of the differential output can increase sensitivity, but also have some ability to offset the additional interference. And some is not a differential output, such as pressure resistance of the output type, you can think is
