C51 verilog 源代码，可以在逻辑中实现51单片机功能

说明：  PID算法用verilog语言实现，实测可用，由三个模块组成(The PID algorithm is implemented in Verilog language. The actual measurement is available. It consists of three modules.)

本程序是锁相环的仿真程序，具有接收端载波同步的功能。注释详尽，程序规范。发端的调制方式有单载波调制，BPSK调制，QPSK调制可供选择。程序中有星座图，锁相环的频差、相差图，以及解调后的基带波形。(This program is a phase-locked loop simulation program, the with carrier synchronization receiving end function. Notes detailed program specifications. The originator of the modulation scheme to choose a single carrier modulation, BPSK modulation, QPSK modulation. Program constellation diagram, the PLL frequency difference, a difference of FIG, and the demodulated baseband waveform.)

Verilog code of SPI configurator for DAC AD7394 and AD7395

Verilog 语言编写 PCI9054 控制器的接口电路，实现 PCI总线到本地 8 位总线的转接控制(The Verilog language writes the interface circuit of the PCI9054 controller to realize the transfer control of the PCI bus to the local 8 bit bus)

频率计VHDL编程。设计一个4位数字显示的十进制频率计，其测量范围为1MHz，测量值通过4个数码管显示以8421BCD码形式输出，可通过开关实现量程控制，量程分10kHz、100kHz、1MHz三档(最大读数分别为9.999kHz、99.99kHz、999.9kHz)； 当输入信号的频率大于相应量程时，有溢出显示。 -Cymometer VHDL programming. Design of a 4-digit decimal display frequency, the measurement range of 1MHz, the measured value through the four LED 8421BCD code shows the form of output can be controlled through the switch range, range at 10kHz, 100kHz, 1MHz Three (maximum reading were 9.999kHz, 99.99kHz, 999.9kHz) when the input signal is greater than the corresponding frequency range, it shows overflow.

This is the source code for I2C(Inter Integreted Circuit) which is used in serial communication

基于Basys3的数字钟实例，主要用于Basys3、vivado开发环境入门。源码使用VerilogHDL(Based on digital clock instance Basys3, mainly for Basys3, vivado development environment started. Use Code VerilogHDL)
