    是否要先打開ALLEGRO? 不需要(當然你的機器須有CADENCE系統(tǒng))。生成完封裝后在你的輸出目錄下就會有幾千個器件(全部生成的話),默認輸出目錄為c:\MySym\. Level里面的Minimum, Nominal, Maximum 是什么意思? 對應ipc7351A的ABC封裝嗎? 是的 能否將MOST, NOMINAL, LEAST三種有差別的封裝在命名上也體現(xiàn)出差別? NOMINAL 的名稱最后沒有后綴,MOST的后綴自動添加“M”,LEAST的后綴自動添加“L”,你看看生成的庫名稱就知道了。(直插件以及特別的器件,如BGA等是沒有MOST和LEAST級別的,對這類器件只有NOMINAL) IC焊盤用長方形好像比用橢圓形的好,能不能生成長方形的? 嗯。。。。基本上應該是非直角的焊盤比矩形的焊盤好,我記不得是AMD還是NS還是AD公司專門有篇文檔討論了這個問題,如果沒有記錯的話至少有以下好處:信號質(zhì)量好、更省空間(特別是緊密設計中)、更省錫量。我過去有一篇帖子有一個倒角焊盤的SKILL,用于晶振電路和高速器件(如DDR的濾波電容),原因是對寬度比較大的矩形用橢圓焊盤也不合適,這種情況下用自定義的矩形倒角焊盤就比較好了---你可以從網(wǎng)上另外一個DDR設計的例子中看到。 當然,我已經(jīng)在程序中添加了一選擇項,對一些矩形焊盤可以選擇倒角方式. 剛才試了一下,感覺器件的命名的規(guī)范性不是太好,另好像不能生成器件的DEVICE文件,我沒RUN完。。。 這個程序的命名方法基本參照IPC-7351,每個人都有自己的命名嗜好,仍是不好統(tǒng)一的;我是比較懶的啦,所以就盡量靠近IPC-7351了。 至于DEVICE,的選項已經(jīng)添加 (這就是批量程序的好處,代碼中加一行,重新生產(chǎn)的上千上萬個封裝就都有新東西了)。 你的庫都是"-"的,請問用過ALLEGRO的兄弟,你們的FOOTPRINT認"-"嗎?反正我的ALLEGRO只認"_"(下劃線) 用“-”應該沒有問題的,焊盤的命名我用的是"_"(這個一直沒改動過)。 部分絲印畫在焊盤上了。 絲印的問題我早已知道,只是盡量避免開(我有個可配置的SilkGap變量),不過工作量比較大,有些已經(jīng)改過,有些還沒有;另外我沒有特別費功夫在絲印上的另一個原因是,我通常最后用AUTO-SILK的來合并相關的層,這樣既方便快捷也統(tǒng)一各個器件的絲印間距,用AUTO-SILK的話絲印線會自動避開SOLDER-MASK的。 點擊allegro后命令行出現(xiàn)E- Can't change to directory: Files\FPM,什么原因? 我想你一定是將FPM安裝在一個含空格的目錄里面了,比如C:\Program Files\等等之類,在自定義安裝目錄的時候該目錄名不能含有空格,且存放生成的封裝的目錄名也不能含有空格。你如果用默認安裝的話應該是不會有問題的, 默認FPM安裝在C:\FPM,默認存放封裝的目錄為C:\MYSYM 0.04版用spb15.51生成時.allegro會死機.以前版本的Allegro封裝生成器用spb15.51生成時沒有死機現(xiàn)象 我在生成MELF類封裝的時候有過一次死機現(xiàn)象,估計是文件操作錯誤導致ALLEGRO死機,原因是我沒有找到在skill里面直接生成SHAPE焊盤的方法(FLASH和常規(guī)焊盤沒問題), 查了下資料也沒有找到解決方法,所以只得在外部調(diào)用SCRIPT來將就一下了。(下次我再查查看),用SCRIPT的話文件訪問比較頻繁(幸好目前MELF類的器件不多). 解決辦法: 1、對MELF類器件單獨選擇生成,其它的應該可以一次生成。 2、試試最新的版本(當前0.05) 請說明運行在哪類器件的時候ALLEGRO出錯,如果不是在MELF附近的話,請告知,謝謝。 用FPM0.04生成的封裝好像文件都比較大,比如CAPC、RES等器件,都是300多K,而自己建的或采用PCB Libraries Eval生成的封裝一般才幾十K到100K左右,不知封裝是不是包含了更多的信息? 我的每個封裝文件包含了幾個文字層(REF,VAL,TOL,DEV,PARTNUMBER等),SILK和ASSEM也是分開的,BOND層和高度信息,還有些定位線(在DISP層),可能這些越來越豐富的信息加大了生成文件的尺寸.你如果想看有什么內(nèi)容的話,打開所有層就看見了(或REPORT) 非常感謝 LiWenHui 發(fā)現(xiàn)的BUG, 已經(jīng)找到原因,是下面這行: axlDBChangeDesignExtents( '((-1000 -1000) (1000 1000))) 有尺寸空間開得太大,后又沒有壓縮的原因,現(xiàn)在生成的封裝也只有幾十K了,0.05版已經(jīng)修復這個BUG了。 Allegro封裝生成器0.04生成do-27封裝不正確,生成封裝的焊盤的位號為a,c.應該是A,B或者1,2才對. 呵呵,DIODE通常管腳名為AC(A = anode, C = cathode) 也有用AK 或 12的, 極少見AB。 除了DIODE和極個別插件以及BGA外,焊盤名字以數(shù)字為主, 下次我給DIODE一個選擇項,可以選擇AC 或 12 或 AK, 至于TRANSISTER我就不去區(qū)分BCE/CBE/ECB/EBC/GDS/GSD/DSG/DGS/SGD/SDG等了,這樣會沒完沒了的,我將對TRANSISTER強制統(tǒng)一以數(shù)字編號了,如果用家非要改變,只得在生成庫后手工修改。

  • JAVA SMPP 源碼

    Introduction jSMPP is a java implementation (SMPP API) of the SMPP protocol (currently supports SMPP v3.4). It provides interfaces to communicate with a Message Center or an ESME (External Short Message Entity) and is able to handle traffic of 3000-5000 messages per second. jSMPP is not a high-level library. People looking for a quick way to get started with SMPP may be better of using an abstraction layer such as the Apache Camel SMPP component: http://camel.apache.org/smpp.html Travis-CI status: History The project started on Google Code: http://code.google.com/p/jsmpp/ It was maintained by uudashr on Github until 2013.

  • 基于多尺度字典的圖像超分辨率重建

    Reconstruction- and example-based super-resolution (SR) methods are promising for restoring a high-resolution (HR) image from low-resolution (LR) image(s). Under large magnification, reconstruction-based methods usually fail to hallucinate visual details while example-based methods sometimes introduce unexpected details. Given a generic LR image, to reconstruct a photo-realistic SR image and to suppress artifacts in the reconstructed SR image, we introduce a multi-scale dictionary to a novel SR method that simultaneously integrates local and non-local priors. The local prior suppresses artifacts by using steering kernel regression to predict the target pixel from a small local area. The non-local prior enriches visual details by taking a weighted average of a large neighborhood as an estimate of the target pixel. Essentially, these two priors are complementary to each other. Experimental results demonstrate that the proposed method can produce high quality SR recovery both quantitatively and perceptually.

  • 基于模糊聚類分析與模型識別的微電網(wǎng)多目標優(yōu)化方法

    在微電網(wǎng)調(diào)度過程中綜合考慮經(jīng)濟、環(huán)境、蓄電池的 循環(huán)電量,建立多目標優(yōu)化數(shù)學模型。針對傳統(tǒng)多目標粒子 群算法(multi-objective particle swarm optimization,MOPSO) 的不足,提出引入模糊聚類分析的多目標粒子群算法 (multi-objective particle swarm optimization algorithm based on fuzzy clustering,F(xiàn)CMOPSO),在迭代過程中引入模糊聚 類分析來尋找每代的集群最優(yōu)解。與 MOPSO 相比, FCMOPSO 增強了算法的穩(wěn)定性與全局搜索能力,同時使優(yōu) 化結果中 Pareto 前沿分布更均勻。在求得 Pareto 最優(yōu)解集 后,再根據(jù)各目標的重要程度,用模糊模型識別從最優(yōu)解集 中找出不同情況下的最優(yōu)方案。最后以一歐洲典型微電網(wǎng)為 例,驗證算法的有效性和可行性。

  • Fundamental Limits on a Class of Secure

    Abstract—In the future communication applications, users may obtain their messages that have different importance levels distributively from several available sources, such as distributed storage or even devices belonging to other users. This scenario is the best modeled by the multilevel diversity coding systems (MDCS). To achieve perfect (information-theoretic) secrecy against wiretap channels, this paper investigates the fundamental limits on the secure rate region of the asymmetric MDCS (AMDCS), which include the symmetric case as a special case. Threshold perfect secrecy is added to the AMDCS model. The eavesdropper may have access to any one but not more than one subset of the channels but know nothing about the sources, as long as the size of the subset is not above the security level. The question of whether superposition (source separation) coding is optimal for such an AMDCS with threshold perfect secrecy is answered. A class of secure AMDCS (S-AMDCS) with an arbitrary number of encoders is solved, and it is shown that linear codes are optimal for this class of instances. However, in contrast with the secure symmetric MDCS, superposition is shown to be not optimal for S-AMDCS in general. In addition, necessary conditions on the existence of a secrecy key are determined as a design guideline.

  • Millimeter+Wave+V2V+Communications

    Recently millimeter-wave bands have been postu- lated as a means to accommodate the foreseen extreme bandwidth demands in vehicular communications, which result from the dissemination of sensory data to nearby vehicles for enhanced environmental awareness and improved safety level. However, the literature is particularly scarce in regards to principled resource allocation schemes that deal with the challenging radio conditions posed by the high mobility of vehicular scenarios
