德州仪器与 DesignSoft 公司联手为我们的客户提供TINA-TI——一个强大的电路仿真工具，适用于对模拟电路和开关模式电
源 (SMPS) 电路的仿真。它是帮助设计师和工程师们进行电路开发与测试的理想选择。
TI 之所以选择TINA?6?4 仿真软件而不是其它的基于 SPICE 技术的仿真器，是因为它同时具有强大的分析能力、简单和直观的
图形界面，并且易于使用，可以让你在最短时间内启动并运行。如果您熟悉其它的 SPICE 仿真器，那么尽快适应TINA-TI 将
会是一个很容易和直接的过程。尽管TINA-TI 是更加强大的 DesignSoft 仿真产品中的一个有限版本，它仍能轻松处理极为复
杂的电路。
德州仪器不确保或支持任何 DesignSoft 的产品。TINA-TI 是由 TI 和DesignSoft 共同开发的软件程序。如需获得 DesignSoft

Tina Pro是一款EDA软件，用于模拟及数字电路的仿真分析。具有交直流分析、瞬态分析、正弦稳态分析、傅立叶分析、可以绘制零、极点图、相量图、等等，功能强大，经过个人使用效果不错，类似的还有软件如multisim，ORCAD的Pspice，采用的模型为标准的Pspice。个人推荐使用此软件，比multisim更接近于实际。现在使用的版本为V8,目前只在电驴里面好像有资源下载。

谢邀，我本科是电子专业的，参加了多年的全国大学生电子设计竞赛，曾获全国一等奖，一路走过来总会有许许多多的教训和经验，我将结合我在竞赛和实践相关的经历，与大家分享一点电子设计入门的经验，如有不妥，欢迎斧正。 1、理论知识与实践的关系 在这个回答里，我非常多的强调了实践的重要性，被一些评论抨击我走了偏路，事实上我不是在否认理论知识（学习成绩）的重要性。我觉得实践中的乐趣可以让你对一门学科更感兴趣同时也能有更感性的认识，而理论知识可以让你在这门学科的研究上走的更长远。实践可以对你的学习起到非常有益的帮助，但这并不代表你要抛弃理论知识。电赛拿国一并且专业排第一的人并不少见，成绩与实践二者并不冲突，完全可以兼顾。 2、工具和技术的关系 本文介绍了许多软件和工具，但是学习技术最重要的不是学习工具本身，而是学习工具背后所代表的那一门技术，例如学习quartus软件其实是为了学习可编程逻辑器件，学习altium designer其实是为了学习PCB电路设计。所以，我们的关注点其实不是怎么学习使用一种软件或者工具而是学习一门技术；掌握工具的操作只是一个开始，后期的实践和经验积累才是核心，电子行业尤其。我们通常说一个人画板子很厉害，不是说他熟练掌握了altium软件的操作，而是说他有着丰富的画板子经验。经验和经历对于硬件工作者非常重要，学会软件后的经验积累才是分化的开始。 【1】单片机设计： 对于电子类专业的学生，我的意见是尽早学习C语言和单片机。C语言是一种目前非常普遍的嵌入式语言，单片机则是一种微型CPU。通过单片机和C语言，你可以实现非常多的功能，具体单片机能做什么，网上的介绍非常多，你可以自行搜索下。 但有一点非常重要，单片机能大一学绝不大二学，能大一上学期学绝不大一下学期学。（事实上这个东西上手非常快） 单片机虽然简单，但是正是它的简单，让人有了学习的欲望，这恐怕是大学学习中最宝贵的东西。其次，单片机的应用可以说贯穿了整个电子类专业学生本科的始末，越早掌握单片机技术，你就会比别人拥有更多的机会，这一点我是有亲身经历的。电子终究是一门实践的技术，找到机会去实践才是不断进步的前提，学会单片机，你就可能比普通人更容易接触老师的项目，更容易参加学科竞赛，从而开始自己的积累，不断进步。 学生能接触到的主流单片机主要包括8位的51单片机、16位的MSP430单片机和32位的STM32单片机，其对应的主要集成开发环境（IDE）分别是KEIL、IAR和KEIL MDK。 当然，提前学习单片机往往是自学，是在本科教学的超前学习（或者说是本科实践教学的滞后），一个人从头学起难度会很大。我只告诉你这些软件的名字当然是没有用处的，下载了这些软件、买了单片机然后呢？没人教学起来可有的难度啊，很多人都是在这里结束了自己单片机生涯。 我的建议是：淘宝网上搜索“51单片机开发板”，然后自行选择一个百元以内的开发板，一定要注意询问店家是否赠送配套的教学视频，否则千万不要购买，这对于初学者和自学者非常重要。 单片机学习主要分四个层次：

Three Good Friends One day, a monkey rides his bike near the river. This time he sees a lion under a tree. The lion runs at him. He is afraid and falls into the river. He can’t swim. He shouts. The rabbit hears him. He jumps into the river. The rabbit swims to the monkey, but he can’t help him. Luckily, an elephant comes along. He is very strong. He helps the rabbit and monkey. Three friends are very happy. They go to the elephant’s home. Then, three of them become good friends. 译文： 三个好朋友 一天，一只猴子在河边骑车。这时他看见树下有一只狮子，狮子向他跑来。他非常的害怕，掉进河里。他不会游泳，大叫起来。兔子听见了，跳进水里，但他却没有办法救猴子。幸运的是，一只大象过来了。大象非常强壮，救出了兔子和猴子。他们来到大象的家，在那里吃了一顿大餐。从此他们成了好朋友。
A Good Boy Little Robert asked his mother for two cents. "What did you do with the money I gave you yesterday?" "I gave it to a poor old woman," he answered. "You're a good boy," said the mother proudly. "Here are two cents more. But why are you so interested in the old woman?" "She is the one who sells the candy." 译文： 好孩子 小罗伯特向妈妈要两分钱。 “昨天给你的钱干什么了？” “我给了一个可怜的老太婆，”他回答说。“你真是个好孩子，”妈妈骄傲地说。“再给你两分钱。可你为什么对那位老太太那么感兴趣呢？” “她是个卖糖果的。”
