数字AGC的源程序

有用的数字钟设计文档，有秒表、闹钟等模块，希望对大家有用！(JUST LEARN FROM IT!!ENJOY!)

The PID controller IP core performs digital proportional–integral–derivative controller (PID controller) algorithm. The algorithm first calculates the error between a measured value (PV) and its ideal value (SP), then use the error as an argument to calculate the manipulate value(MV). The MV will adjust the process to minimize the error. It can be used to calculate duty cycle for PWM (Pulse Width Modulation).

说明：  交通灯的控制，分主干道和从路交通灯，主路优先，正常情况下，绿灯60s，红灯30S，黄灯5S(Traffic light control)

说明：  实现二项混合式步进电机的驱动，和步进电机的细分程序。(The driving of binomial hybrid stepper motor and the subdivision program of stepper motor are realized.)

低通滤波器用于的加强频率选择方案中的任何信号，所以这段代码将帮助他们选择他们各自设计的频率到一个特殊频率为界

HART 官方资料-HART协议采用基于Bell202标准的FSK频移键控信号，在低频的4-20mA模拟信号上叠加幅度为0.5mA的音频数字信号进行双向数字通讯，数据传输率为1.2kbps。(Official information-HART HART protocol based Bell202 standard frequency shift keying FSK signal at low frequencies 4-20mA analog signal amplitude is 0.5mA superimposed on the two-way audio digital signal digital communication, data transfer rate of 1.2kbps.)

用Hspice实现一个三输入异或门，并分析其功耗和延时。(A three input XOR gate is implemented by Hspice, and its power consumption and delay are analyzed.)

Verilog实现FPGA的VGA塞瑟条纹显示代码，测试完全正确，可以成功的实现功能。

下面的文件，包括各种RTL代码一样，全加器，defparam例如，还包括位运算符，逻辑运算符和多家运营商，半加器，复用器，多路复用器。这可能会帮助你理解的Verilog整个概念。

Altera SOPC 开发套件，它用 verilog 语言开发。它是有用的 EDA 设计倾向。有三个完整的示例的 SDRAM，led 灯和内皮祖细胞。有逻辑的设计举例。
