和声的图形产生一个叫做“LabARIa”和“HAL”的文件夹。请参阅附件屏幕截图。我用英语字典检查了“LiBARA”和“HAL”。但是英语字典什么都不教我。似乎这些都是缩写词。我不是英语本族语者。你是什么意思“LIBARIAL”?你说“哈尔”是什么意思?这些词的由来是什么?任何建议都让我高兴。 以上来自于百度翻译 以下为原文 Graphics of Harmony generates the folder called "libaria" and "hal" . Please see the attached screenshot.I examined "libaria" and "hal" by using English dictionary.But English dictionary teach me nothing.It seems that these are something like abbreviation.I am not native English speaker.What do you mean "libaria" ?What do you mean "hal" ? What is origin of these words ?Any advise make me pleased.ysaito Attached Image(s)[img][/img]

大家好: 我有一个关于成本表/额外成本表配置和真实PR策略的问题。 在我的项目中,LUT的使用率约为70 +%,并始终满足PR问题。它报告:警告:路由:464- 路由器检测到非常密集,拥挤的设计。路由器极不可能完成设计并满足您的时序要求...... blablablabla 我向同事或其他论坛寻求帮助,并被告知,不同的成本表/额外成本表映射了不同的PR策略。在我更改配置后,是的,有时PR可以完成。 但每次,我只是盲目地循环所有组合,直到得到一个好的组合:10/11/12/13/14/15/20/21 /.../ 25/30 / ......有时我有不幸的是,尝试超过50次测试。那么有人可以给我一些建议: 1.成本表意味着什么? - 我被告知它意味着随机种子的数量,或某些方程的参数,对吧? 2.额外费用表意味着什么? - 它的范围从0到5,而5意味着最大的努力将用于PR? 3.一个固定的成本表设置&&不同的额外成本表设置意味着“具有不同公关努力的固定公关策略”? 4.对于464号公路警告,我应该使用哪种方法?是否有默认解决方案,或者我必须盲目地一遍又一遍地进行测试? 这个问题困扰了我很长一段时间,我真的很期待你的所有建议和帮助。谢谢!以上来自于谷歌翻译以下为原文Hi all:I have a question about cost-table/extra-cost-table configuration and real PR strategy.In my project, the LUT usage is about 70+%, and always meet PR issues. It reports: WARNING:Route:464 - The router has detected a very dense, congested design. It is extremely unlikely the router will be able to finish the design and meet your timing requirements...... blablablabla I asked help from colleagues or via other forums, and was told that, different cost-table/extra-cost-table maps different PR strategy. After I changed the configuration, yes, sometimes PR can finish. But everytime, I was just looping all the combinations blindly until got a good one: 10/11/12/13/14/15/20/21/.../25/30/......Sometimes I had to try over 50 tests, unfortunatly. So could anyone please give me some advices that: 1. cost-table means what? -- I was told it means the number of random seeds, or parameters of some equation, right? 2. extra-cost-table means what? -- it ranges from 0 to 5, and 5 means the most effort will be used for PR? 3. one fixed cost-table setting && different extra-cost-table setting means "a fixed PR strategy with different PR effort"? 4. for the Route 464 warning, which stratery should I use? Is there a default solution, or I have to test over and over again blindly? This question bothers me quite a long time, and I am really expecting all your suggestions and help. Thanks!

作者:张水苹摘要VDMR8M32是珠海欧比特公司自主研发的一种高速、大容量的TTL同步静态存储器(MRAM),可利用其对大容量数据进行高速存取。本文首先介绍了该芯片的结构和原理,其次详细阐述了基于magnum II测试系统的测试技术研究,提出了采用magnum II测试系统的APG及其他模块实现对MRAM VDMR8M32进行电性测试及功能测试。其中功能测试包括全空间读写数据0测试,全空间读写数据1,以棋盘格方式进行全空间读写测试。另外,针对MRAM的关键时序参数,如TAVQV(地址有效到数据有效的时间)、TELQV(片选使能到数据有效的时间)、TGLQV(输出使能到输出数据有效的时间)等,使用测试系统为器件施加适当的控制激励,完成MRAM的时序配合,从而达到器件性能的测试要求。

嗨,我使用ISE12.3(Virtex6设备)并在我们的设计上多次尝试,所有PAR结果都是不完全路由的信号。我发现时间限制不符合保持时间问题(差异-0.018ns)。如何检查此问题以及综合,PAR或设计代码中的任何建议,谢谢。·乔维以上来自于谷歌翻译以下为原文Hi, I use ISE12.3(Virtex6 device) and try many times on our desing, all the PAR results are singnals not completely Routed.I found the timing constrains not meet that are hold time issue (difference -0.018ns).How to checkthis problem and any suggestion in synthesis, PAR or desing code, thanks.
