 随着电子技术的不断革新和芯片生产工艺的不断提高，印制电路板（PCB）的结构变得越来越复杂，从最早的单面板到常用的双面板再到复杂的多层板，电路板上的布线密度越来越高，同时随着DSP、ARM、FPGA、DDR等高速逻辑元件的应用，PCB的信号完整性和抗干扰性能显得尤为重要。依靠软件本身自动布局布线无法满足对板卡的各项要求，需要电子设计工程师具备更高的专业技术水平，同时因为EDA软件更新换代越来越快，需要工程师们来深挖新版本EDA软件的各种功能技巧，提高设计的效率。<br \/><br \/>      采用Cadence  Allegro为工具进行原理图设计、PCB设计是电子信息类、电气信息类专业的一门实践课程，也是电子设计最常用设计工具之一，面对信息化社会中电子应用领域的不断扩大，本套课程以职业岗位分析为依据，用“真实产品为载体”、“实际项目流程为导向”，基于<b>全新的Cadence 23.1-Allegro X软件进行录制的<\/b>，我们将从最开始的软件安装激活开始，一步步深入讲解一个电子产品开发所包含的<b>95%以上操作<\/b>，学员跟着本套课程进行实操学习，能够快速掌握本Cadence  Allegro这款EDA工具的使用。<\/font><\/p><p><br \/><\/p><p><b><font size=\"4\">点击下载：<\/font><\/b><\/p><p><font
