PRO\E4.0安装方法 第一步:修改环境变量. 我的电脑----属性---高级---环境变量---新建---变量名:lang 值:chs (注:下载好的PRO/E有CD1 CD2 CD3 crack4.0) 第二步、许可证生成 在D盘新建一个文件夹PROE,再在PROE里面新建文件夹,命名为proewildfire,将安装文件里面的CRACK4.0文件夹复制到PROE里面,用记事本打开CRACK里面的PTC-LIC-4.0文件,你就找下HOSTID:00-11-D8-BB-5B-62,将00-11-D8-BB-5B-62复制起来,然后点击CD1- sutep(如果没有反应,找到CD1-dsrc--i486-nt----obj---PTCSETUP安装),安装界面会出现你的主机ID,把记事本里面的ID全部替换为你的主机ID(方法:编辑---替换,然后按要求选择填选,全部替换),保存(记得存在哪。等等有用)。

现代的电子设计和芯片制造技术正在飞速发展,电子产品的复杂度、时钟和总线频率等等都呈快速上升趋势,但系统的电压却不断在减小,所有的这一切加上产品投放市场的时间要求给设计师带来了前所未有的巨大压力。要想保证产品的一次性成功就必须能预见设计中可能出现的各种问题,并及时给出合理的解决方案,对于高速的数字电路来说,最令人头大的莫过于如何确保瞬时跳变的数字信号通过较长的一段传输线,还能完整地被接收,并保证良好的电磁兼容性,这就是目前颇受关注的信号完整性(SI)问题。本章就是围绕信号完整性的问题,让大家对高速电路有个基本的认识,并介绍一些相关的基本概念。
