FPGA 出租计费器

实现pwm波的输出，按键可调占空比的，可通过连接pwm输出值led灯以检测占空比的变化(To realize the output of the PWM wave, key adjustable duty ratio, but through the connection PWM output value led lamp with testing duty ratio changes )

It is Synopsys dmac controller databook

Arty Z7 20 HDMI output

VHDL数字系统设计和工程实践5，包含原理，真值表和原理图，以及VHDL源代码.-VHDL digital system design and engineering practice 4, including the principles, truth table and schematic, as well as VHDL source code.

基于FPGA的神经网络硬件实现中的关键问题研究，适合用fpga研究神经网络的工程人员参考-FPGA-based hardware implementation of neural networks in the study of key issues for research with neural networks fpga reference works

说明：  可以实现2PSK的信号调制，已经过Modelsim波形仿真(It can realize 2PSK signal modulation and has been simulated by Modelsim waveform.)

说明：  在FPGA内利用verilog实现数字上变频(apply the verilog to implement the digital up frequency)

说明：  实现UDP的网络传输，在PC建立UDP的服务器，向fpga的ip：192.168.0.25发送数据，实现回环通讯。(The network transmission of UDP is realized. UDP server is set up in PC, and the data is sent to IP: 192.168.0.25 of FPGA to realize loop communication.)

参数化FFT源代码，点数和位宽可变，内附testbench和说明文档-parameters of the source code FFT, counting and variable bit-enclosing testbench and documentation

说明：  基于sv的uvm平台搭建实战，对于验证方法学来说，分层的测试平台是一个关键的概念。虽然分层似乎会使测试平台变得更复杂，但它能够把代码分而治之，有助于减轻工作负担，而且重复利用效率提升。验证平台可以类似分为五个层次：信号层、命令层、功能层、场景层和测试层。(Construction of UVM platform based on SV)
