关于vhdl的一些例子

简易函数发生器，能产生正弦波，三角波，梯形波，方波，并且可调频率和幅度值。(Simple function generator can produce sine, triangle wave, trapezoidal wave, square wave, and the adjustable frequency and amplitude values.)

程序设置了fpga 的 5x5点阵驱动程序，代码相对比较简洁，这个程序可以作为fpga输出控制，驱动稳压芯片工作，进而点灯

基于FPGA的7x7块交织器设计，程序分交织、解交织两部分，并在QUARTUS II 9.0 下仿真通过，内附模块详细端口说明及仿真分析文件。

GAL16V8(仿真74LS138),试验通过。包括able及jed文件。对pcb印板设计时，对简化走线特别有用。简单的修改GAL16V8程序，可灵活地进行地址译码修改。(GAL16V8 (simulation 74LS138), test passed. Including the able and jed file. Printed on the pcb board design, especially useful to simplify alignment. Simple modifications GAL16V8 program, the flexibility to change the address decoding.)
