FPGA_正反_可变步长_计数器

本RAR包括《Verilog-HDL实践与应用系统设计》一书中的全部例子，这些例子全部通过了验证。第七章以后的设计实例，不仅有Verilog-HDL的例子，也附了包括VB、VC++等源程序,甚至将DLL的生成方法也详尽地作了说明。(The RAR includes " Verilog-HDL Practice and Application of system design," a book full of examples, all passed validation. Chapter VII of the future design examples, not only examples of Verilog-HDL, but also attached, including VB, VC++ source code, etc., and even DLL generation methods explained in detail.)

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.)

如果需要用verilog设计一项比较简单的功能，那么这个浅显易懂的程序能让你很快明白点阵的设计方法，尤其是对那些初学者(If you need to use a relatively simple verilog design features, then this easy to understand design of the program allows you to quickly understand the lattice method, especially for those who are beginners)

基于sopc的lcd时钟，开发工具为nios ii和quartus ii9.0(Based on sopc the lcd clock, development tools for the nios ii and quartus ii9.0)

简单的12位的AD转换实现，开发平台为vivado，开发语言为verilog。

使用Verilog编写的时间同步模块，解决位同步问题，ISE12.2下编译通过(Time synchronization module written in Verilog, bit synchronization issues under ISE12.2 compiled by)

DSP与FPGA时序接口模块，已经经过测试，保证读写稳定(The Interface of DSP to FPGA)
