Altium Desig ner设计报错问题总结在编译原理图时，引脚和连线旁边出现很多红线，提示erro r：signal withn odriv er。
原理图没有加入到Pro ject里。
第一次导入没问题，但是改了个元件的封装，在更新一下（Design—Update SCH），点击导入时出现Unko wnPin。
解决方案一：把第一张PC B删掉，新建一个PC B再倒入。
解决方案二：把改过的元件在PCB中删除，再倒入。
以上问题本应该是没问题的，但是可能是我们使用的盗版软件的原因。
用altiu mdesi gner画完图编译后，出现几百警告，几乎的所有的都是Offgridp in 画的图在项目中去编译，的不能编译，如果文件不在项目中的话，就会出现你说的不在网络的提示。
你的元件没有在原理图上真正形成电气上的连接。
你的元件库没有被软件别。
没有你建一个项目文件，把你的原理图放在里去做编译，这样就不会出错了。
是因为你原理图中的元件引脚尺寸和你设置的栅格尺寸不对应，导致系统无法识别而报错，引脚长度尺寸必需设置成栅格尺寸的整数倍！！！你把你做的原理图元件重新再画一遍，再编译，问题解决！！!双面板应该都有哪些La yer?B ottom Layer底层铜皮，双面板必须要T opLay er顶层铜皮，双面板必须要T opOve rLaye r顶层丝印，一般需要，也有节约成本不做的。

1.BO有哪些报表工具，各有什么特点？2.Universe有何作用？答：Universe的作用是为WEB intelligence的非技术用户提供一个易于使用的理解的接口，使他们能依据数据库运行查询，以创建报表和执行数据分析。
作为Universe设计员，使用Designer来创建表示数据库结构的对象（例如列和数据库函数），用户需要访问和查询这些对象，来获得满足其业务需求所需的对象。
您在Universe中创建的对象必须和最终用户的业务环境和词汇相关。
这些对象的作用是将以业务为焦点的前端呈现为数据库中的SQL结构。
3.介绍一下Universe，有哪些对象？2.称为对象的SQL结构，映射到数据库中的实际SQL结构，如列、表和数据库函数。
对象按类分组。
WEB intelligence 用户既可以看到对象，也可以看到类。
3.在数据库中使用的表和联接的模式。
对象是通过您包括在模式中的数据库结构来构建的。
模式只能由designer用户使用。
WEB intelligence和desktop intelligence 用户看不到模式。
WEB intelligence 用户连接到universe，并依据数据库运行查询。
他们可以进行数据分析，并使用universe 中的对象创建报表，而无需看到或了解有关数据库中的基本数据结构的任何信息。
Universe由对象和类组成。
类是Universe中的对象的逻辑分组，表示对象的类别。
类相当与windows环境中的文件夹，通常映射到Universe模式的表。
对象：是映射到数据库中的数据或数据派生的命名Universe单元，应根据目标用户组的业务词汇命名对象的名称。
每个对象都映射为Universe模式中的一个列，并推导出一个Select语句（在查询中使用）对象：度量、明细、对象（维）。
维：用于分析的参数，通常与地理、产品或时间的层次相关。
明细：提供维的说明，但并不是分析的焦点，例如（电话号码）度量：传递用于确认维对象数量的数值信息。

SABER仿真中6种常犯错误的解决SABER仿真中6种常犯错误的解决Saber是目前电子设计领域当中应用较为广泛的也是功能最为全面的仿真软件之一。
但对于新手来说，在Saber软件的使用过程中总会遇到这样或那样的问题，阻碍设计与学习。
在本文中，小编特意为大家总结了一些在saber仿真中常见的问题及解决方法。
1、设置元件属性时误加单位。
这当然会导致Saber出现错误。
此问题经常出现在初学者身上。
2、元件名文件名路径名有重复，saber也会报错。
3、***errorAlg_no_solution***Cannotfindnonlinearsystemsolution ***errorAlg_iterations***Toomanyiterations常用的方法是增大targetiterations和maxnewtoniterations，有时减小trunctionerror也同样可行，一般都能解决报错的问题。
4、***ERRORALG_SINGULAR_JACOBIAN***SingularJacobianmatrix 遇到此问题时最好先看是否有自建的模型，有极大的可能性是模型错误，如果确定无误或没有，再对接地进行确认，saber中无法存在独立的系统，因此即使隔离也需要共地。
5、出现电压环路电流环路。
解决方法：给电容电感加初始值;或者并联一个很大的电阻串联很小的电阻进行仿真，再将电阻去掉后就会恢复正常。
6、模型越界。
遇到此类情况就需要仔细检查电路了。
saber用户指南dc一章也对调试方法进行了讲解，感兴趣的朋友可以看一看。
以上六点就是新手们在使用saber仿真时非常常见的几种问题，本文对这6 个问题逐一进行了介绍，并附上有效地解决方案。
大家在进行saber仿真之前不妨花上几分钟来阅读本文，以此来避免一些不必要的错误发生。
习题参考答案说明：给出了简答、叙述类习题的参考答案，为避免误导或限制读者解决问题的思路，未给出操作与演示类习题的参考答案，不过其中的大部分演示类习题操作过程书中均详细介绍过。
习题11-1电子线路CAD的基本含义是什么？CAD软件包必须具备哪些功能？答：电子线路CAD的基本含义是使用计算机来完成电子线路设计的过程，包括了元件电气图形符号创建、电原理图(逻辑电路图)的编辑、电路功能仿真、工作环境模拟、PLC以及PFAG器件仿真与编程、印制板设计（自动布局、自动布线）与检测（布局、布线规则的检测和信号完整性分析）等。

Interested,you stop and read the poster：Hello and welcome to World Book DayWorld Book Day is here to change livesthrough a love of books and sharedreading,and bring books to the childrenwho need them most.World Book Day isan excellent chance for everyone tocelebrate the joy of reading.●Share A Story Live-our exciting digitalevents programme beaming authors （作家）straight into your school.●Raising money,raising readers-our fundraising ideas to help us change lives through reading.●World Book Day Book Club-a new online reading community.●Share A Story Corner-stories to encourage families to read together.Happy World Book Day!For up-to-date information,visit our website !26.World Book Day is a special day for people to ______ .A. celebrate the joy of readingB. change lives by raising moneyC. meet famous authors at homeD. enjoy writing in local communities27.According to the poster,if you want to read stories with your parents,you can join ______ .A. Share A Story LiveB. Share A Story CornerC. World Book Day Book ClubD. Raising money,raising readers28.The designer uses words and pictures in the poster to ______ .A. catch readers' attentionB. encourage families to write booksC. help readers form reading habitsD. recommend different types of booksBAccording to a research,more than 130 billion pounds of uneaten food go to waste in Laura's country each year.That is about 30% of the yearly food supply（供应）.It is a sad fact,especially when you consider how many families and homeless people are in hunger.When Laura saw her school dining hall throw away food that was not eaten at all every day,she came up with an idea.She started a project to help her school dining hall to give away uneaten food to homeless shelters （庇护所）in her community.In the past three years,the same project has spread to other schools and some fast food restaurants throughout the city.The project is called Feed & Find,and has already fed thousands of people in her city.How does it work？Through an app,Feed & Find matches local homeless shelters with school dining halls and restaurants that have uneaten food to provide.When dining halls or restaurants have uneaten food left,they can use the app to share the information about the food.A truck driver working for the project is then sent to pick it up and take it to a shelter.Pretty cool,right？It's not surprising that people in other cities have got in touch with Laura,hoping that she could help develop similar projects for their communities.Some people,however,have concerns about the safety of the uneaten food.They think such food may not be clean enough.Still,this project is a clever way to help solve the problem,of food waste and it helps those in need.29.The numbers in Paragraph One tell us ______ .A. some people are poorB. food waste is seriousC. the population is largeD. the research is interesting30.People in other cities would like Laura to ______ .A. find a truck driverB. visit their communitiesC. give away food to themD. help develop projects like hers31.The underlined word " concerns" in this passage means ______ .A. waysB. secretsC. worriesD. decisionsCShashiyu was once a poor village in Hebei Province,but now it has changed into a rich and livable place.In the 1940s,villagers in Shashiyu had little food and few clothes,but they had a strong wish for a better life.Zhang Guishun,the Party secretary of Shashiyu,encouraged his villagers to do their best to pull themselves out of poverty, "In the ancient Chinese story,Yu Gong could move mountains with his strong will and hard work,why can't we？Nobody was born to be poor？" Hearing his words,the villagers decided to make a difference.Led by the Communist Party of China （中国共产党），the villagers carried water and soil to their village from faraway places to improve their land.From 1966 to 1971，they reclaimed （开垦）lots of land and greatly improved their life.However,the village encountered a new problem two decades later as the environment became heavily polluted by chemical plants （化工厂）and mine refineries （冶炼厂）built in 1990s.The polluting factories were shut down in 2004，and villagers started grape cultivation,which soon became a main industry in Shashiyu.In 2009，the city-level government invested over 1 million yuan （＄152.723）to change the village's exhibition hall into a museum in memory of development efforts made by earlier generations.After 10 years,the village was called "National Forest Village".Zhang said that the village started a yearly tourism festival in 2015 to attract travelers to pick grapes. "The grapes could be sold at a better price once Shashiyu becomes famous through this festival.Our villagers can then live even better lives," he said.32.From 1966 to 1971，what did the villagers do to improve their living situation？______A. They planted grapes to earn money.B. They carried water and soil to their village to improve their lands.C. They moved to another place to live a better life.D. They built a lot of factories.33.When was Shashiyu called "National Forest Village"？______A. In 2009.B. In 2004.C. In 2015.D. In 2019.34.Where can you probably read the passage？______A. In a storybook.B. In a newspaper.C. In a sports magazine.D. In a science book.DHave you ever heard voices from the universe？What secrets lurk （潜藏）in the signals of pulsars （脉冲星Y 16，000 light-years from Earth？Our eyes may not be able to explore these distant mysteries,but "Sky Eye" allows us to "see" farther.China's Five-hundred-meter Aperture Spherical Radio Telescope （望远镜）（FAST），commonly known as"Sky Eye"，the world's largest single-aperture （单口径）radio telescope,officially opened to the world on March 31.The giant telescope is the size of 30 soccer fields. "Before FAST was put into use,China's radio telescopes usually had a diameter of fewer than 50 meters," said Wang Qiming,FAST's chief technologist."FAST marks a huge leap （飞跃）forward"Not only is the telescope leading in size,but it's also leading in terms of sensitivity （敏感度）.FAST is about 2.5 times as sensitive as the second-largest telescope in the world,the Arecibo,Observatory in Puerto Rico,and can "see" objects some 13.7 billion light-years away,reported Shine,a Shanghai-based media platform.That is to say,if you make a phone call from the moon,it can detect the signal,according to CNR News.Since its completion in September 2016，it has found more than 300 pulsars （脉冲星）-objects thought to be rapidly rotating neutron （中子）stars that emit （发射）regular pulses （脉冲）of radio waves.To date,FAST has expanded（扩大）four times the volume of the space range that radio telescopes can effectively explore,which means that scientists can discover more unknown cosmic （宇宙的）phenomena （现象），according to Shine.Experts believe"Sky Eye" will surprise us in the future."FAST has the potential （潜力）to detect signals from thousands of superior planets.Maybe aliens with much more advanced technologies live there," Li Di,chief scientist of FAST，told China Daily."TAST may well be the instrument （仪器）enabling great discoveries,perhaps even discoveries that will earn Nobel or other,significant prizes," Sheldon Glashow,winner of the 1979 Nobel Prize in Physics,told China Daily.He also has high expectations （期望）for FAST. Now "Sky Eye" has changed from "China's eye" to" the world's eye".About 10 percent of FAST's observation （观测）time in the first year,roughly 450 hours,is expected to be allocated （分配）to foreign scientists,said Li Di."FAST provides astronomical （天文的）capabilities not available anywhere else in the world.Astronomers and physicists who need those capabilities will surely take advantage of China's generosity in making the tools widely available,Joseph Taylor Jr.，recipient of Nobel Prize in Physics in 1993，told China Daily.35.What does the article tell us about FAST？______A. It is about 2.5 times as large as Arecibo.B. It can "see" objects 30 million light- years away.C. It helped Chinese physicists win a Nobel Prize.D. It has been available to foreign scientists since March 31.36.What has FAST allowed scientists to do？______A. Send pulses of radio waves into the universe.B. Know more about pulsars in the universe.C. Answer phone calls from the moon. .D. Change the way neutron stars emit pulses.37.What is the main purpose of the article？______A. To compare FAST and Arecibo.B. To describe how FAST works.C. To introduce a new way to observe neutron stars.D. To inform readers of advantages and potential use of FAST.四、任务型阅读-简答（本大题共1小题，共6.0分）38.请认真阅读下面短文，用英语回答短文后的问题。
电气检测时出现Hole Size Constraint (Min=1mil) (Max=100mil) (All)怎么处理最佳答案导致出现这个错误的原因就是由于你的PCB中钻孔的尺寸与PCB规则中的设定尺寸冲突。
解决方法有两个：1）更改规则检查内容，不再上报钻孔尺寸错误冲突。
具体方法就是：快捷键 T D 打开规则检查窗口，在Rules To Check中，将Hole Size后面两个框内的勾去掉，这样就不会再报此类错误。
2）更新钻孔尺寸规则，让你的钻孔正常化。
具体方法是：快捷键 D R 打开规则编辑窗口，在Design Rules内找到 Hole Siz e并双击打开进行规则编辑；将最大值和最小值更改为包含你的PCB上钻孔的最大尺寸和最小尺寸后即可。
un-routed net constraint ( (all) )错误T+D,工具里面的设计规则检查ALTIUM DESIGNER 导入PCB时提示some nets were not able to matched.Try to match these manualy?具体解决方案如下：解决方案1：然后新建一个PCB文件，再次更新的时候就会出现这个问题。
发表一下个人意见，然后你有更改过原理图的某些网络。
你原先更新过一次PCB，可以将工程中的PCB文件删除，在确认封装等没有问题的情况下，再UPDATE PCB DOCUMENT就行了兄弟我也是用AD6的，是个菜鸟解决方案2：刚刚试了一下，再UPDATE PCB DOCUMENT就行了慢慢摸索吧，有些问题很难说请，可以将工程中的PCB文件删除，然后新建一个PCB文件，在确认封装等没有问题的情况下silk to silk (clearance=10mil)报错Altium Designer PCB中显示SilkToSilkClearance和Silkscreen ComponentPad Clea rance的距离怎么取消？例如字符间距设置的是0.254mm，PCB 字符之间就会出现<0.254mm这样的白色字。
