8选1程序，是利用vhdl编写的，自己弄得还能用，上传下(8 Select a program is written using vhdl, allowed herself can use to upload the next)

VHDL语言编写的I2C通信接口,可与单片机等MCU相连,只占用很少的引脚线完成数据的传输(Written in VHDL I2C communication interface, such as MCU and MCU can be connected, only takes a few lines to complete the data transmission pin)

verilog 教程 PPT版本 语法 结构 设计技巧等(Verilog tutorial PPT version)

使用verliog实现ps2键盘接口的驱动，通过altera cyclone 第四代验证通过(Use verliog implement ps2 keyboard interface driven by a fourth-generation verified by altera cyclone)

this is "AND" gate implementation in VHDL

altera详细使用配置手册，有一定的参考价值，写的比较详细-altera in detail the use of manual configuration, has a certain reference value, a more detailed written
