FPGA使用Xilinx复位

目前最新的OVL库，里面是标准的ASSERTION模块，支持VHDL刚Verilog，最近在做AXI协议验证的时候用到，分享下(The latest OVL(open verification library),including all standard module of assertions(VHDL and Verilog). It can be used into AXI Protocl Verification. Just share with you guys.)

Coding Styles for if Statements and case Statements

基于uc3842的反激电路的saber仿真模型，可调制，波形结果完美(The saber of the flyback circuit simulation model based on uc3842, modulation, waveform perfect results)

lattice ECP3系列高速FPGA serdes测试代码(lattice ECP3 series high speed serdes test code)

采用FPGA实现的DDS波形发生器源码，可以实现频率幅值变换、正弦波、方波、三角波输出，输出频率可达1MHz(FPGA implementation of the DDS waveform generator source frequency amplitude transform, sine wave, square wave, triangle wave output, the output frequency up to 1MHz)

基于Verilog的串口通信源码 ，实现串口通信功能(Verilog source code based on serial communication)

本程序设计一个基于FPGA的4相步进电机定位控制系统。由步进电机方向设定电路模块、步进电机步进移动与定位控制模块和编码输出模块构成。前两个模块完成电机旋转方向设定，激磁方式设定和定位角度的换算等工作，后一个模块用于对换算后的角度量编码输出。-This procedure to design an FPGA-based 4-phase stepper motor positioning control system. Direction set by the stepper motor circuit module, stepper motor stepper movement and positioning control module and the code output modules. The first two modules complete the motor rotation direction setting, exciting way of setting the angle and positioning of the conversion work, after a module for the point of view of the volume of converted output encoding.

对pci9054芯片的配置进行了设置，并对PCI9054的各状态机进行了设置，程序经过了测试(Pci9054 chip on the configuration of the set, and each state machine PCI9054 been set, the program have been tested)

基于VHDL语言的波形发生器编程设计，能够实现常用波形的产生。(Waveform generator design based on VHDL programming, to achieve common waveform generated.)
