四位密码锁

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.)

资源描述 说明： 结绳模块(Pluse2Toggle): 负责延长待采样信号 同步模块(Synchronization)：负责双触发器锁存 解绳模块(Toggle2Pluse)： 负责将长信号转换成脉冲信号 支持信号从快时钟域到慢时钟域，也支持信号从满时钟域到快时钟域，

说明：  Verilog学习文档，介绍基本知识点，语言要素(for learning Verilog)

VHDL语言，设计一个在DE2平台的8个七段数码管上循环显示HELL0的程序，采用按键控制循环的速度，慢速循环时间间隔为1S，快速循环时间间隔为200ms。(VHDL language, design a platform in the DE2 8 segment digital tube display HELL0 program cycle, the speed control loop using keys, slow cycle time interval for the 1S, fast cycle time interval is 200ms.)
