论文摘要
电子技术获得了飞速的发展，在其推动下，现在电子产品几乎渗透了社会的各个领域，有力地推动了社会生产里的发展和社会信息化程度的提高，同时也是使现代电子产品性能进一步提高，产品更新换代的节奏也越来越快。首先EDA技术在进入21世纪后，得到了很大的发展，其基本特征是采用高级语言描述，具有系统级仿真和综合能力。VHDL硬件描述语言是设计源文件可以采用类似与C语言的书写形式，并采用结构设计方法。随着人们生活水平的提高，密码锁作为家庭防盗卫士的作用日趋重要，它与普通机械锁相比有一些独特的优势，如：保密性强，防盗性能好，可以不用钥匙，只要记住密码即可开锁。
Abstract
The electronic technology has obtained the rapid development, under its impetus, the electronic products nearly seeped society's each domain now, powerfully impelled in the social product development and the social becoming an information based society degree enhancement, simultaneously also is makes the modern electronic products performance further to enhance, the product renewal rhythm more and more is also quick. First the EDA technology after enters for the 21st century, obtained the very big development, its basic characteristic uses the higher order language description, has System the simulation and the synthesizing capacity. The VHDL hardware description language is designs the source document to be possible to use is similar with the C language written form, and uses the structural design method. Along with the people living standard enhancement, the password lock took the family security bodyguard's function is day by day important, it compared to has some unique superiority with the ordinary mechanical phase-lock, for example: Secret, the security performance is good, may not use the key, so long as remembers the password then unlock.
