  • Testbenches have become an integral part of the design process, enabling you to verify that your HDL

    Testbenches have become an integral part of the design process, enabling you to verify that your HDL model is sufficiently tested before implementing your design and helping you automate the design verification process. It is essential, therefore, that you have confidence your testbench is thoroughly exercising your design. Collecting code coverage statistics during simulation helps to ensure the quality and thoroughness of your tests.

  • PCB設(shè)計(jì)問(wèn)題集錦

    PCB設(shè)計(jì)問(wèn)題集錦 問(wèn):PCB圖中各種字符往往容易疊加在一起,或者相距很近,當(dāng)板子布得很密時(shí),情況更加嚴(yán)重。當(dāng)我用verify Design進(jìn)行檢查時(shí),會(huì)產(chǎn)生錯(cuò)誤,但這種錯(cuò)誤可以忽略。往往這種錯(cuò)誤很多,有幾百個(gè),將其他更重要的錯(cuò)誤淹沒(méi)了,如何使verify Design會(huì)略掉這種錯(cuò)誤,或者在眾多的錯(cuò)誤中快速找到重要的錯(cuò)誤。    答:可以在顏色顯示中將文字去掉,不顯示后再檢查;并記錄錯(cuò)誤數(shù)目。但一定要檢查是否真正屬于不需要的文字。 問(wèn): What’s mean of below warning:(6230,8330 L1) Latium Rule not checked: COMPONENT U26 component rule.答:這是有關(guān)制造方面的一個(gè)檢查,您沒(méi)有相關(guān)設(shè)定,所以可以不檢查。 問(wèn): 怎樣導(dǎo)出jop文件?答:應(yīng)該是JOB文件吧?低版本的powerPCB與PADS使用JOB文件。現(xiàn)在只能輸出ASC文件,方法如下STEP:FILE/EXPORT/選擇一個(gè)asc名稱/選擇Select ALL/在Format下選擇合適的版本/在Unit下選Current比較好/點(diǎn)擊OK/完成然后在低版本的powerPCB與PADS產(chǎn)品中Import保存的ASC文件,再保存為JOB文件。 問(wèn): 怎樣導(dǎo)入reu文件?答:在ECO與Design 工具盒中都可以進(jìn)行,分別打開(kāi)ECO與Design 工具盒,點(diǎn)擊右邊第2個(gè)圖標(biāo)就可以。 問(wèn): 為什么我在pad stacks中再設(shè)一個(gè)via:1(如附件)和默認(rèn)的standardvi(如附件)在布線時(shí)V選擇1,怎么布線時(shí)按add via不能添加進(jìn)去這是怎么回事,因?yàn)橛袝r(shí)要使用兩種不同的過(guò)孔。答:PowerPCB中有多個(gè)VIA時(shí)需要在Design Rule下根據(jù)信號(hào)分別設(shè)置VIA的使用條件,如電源類只能用Standard VIA等等,這樣操作時(shí)就比較方便。詳細(xì)設(shè)置方法在PowerPCB軟件通中有介紹。 問(wèn):為什么我把On-line DRC設(shè)置為prevent..移動(dòng)元時(shí)就會(huì)彈出(圖2),而你們教程中也是這樣設(shè)置怎么不會(huì)呢?答:首先這不是錯(cuò)誤,出現(xiàn)的原因是在數(shù)據(jù)中沒(méi)有BOARD OUTLINE.您可以設(shè)置一個(gè),但是不使用它作為CAM輸出數(shù)據(jù). 問(wèn):我用ctrl+c復(fù)制線時(shí)怎設(shè)置原點(diǎn)進(jìn)行復(fù)制,ctrl+v粘帖時(shí)總是以最下面一點(diǎn)和最左邊那一點(diǎn)為原點(diǎn) 答: 復(fù)制布線時(shí)與上面的MOVE MODE設(shè)置沒(méi)有任何關(guān)系,需要在右鍵菜單中選擇,這在PowerPCB軟件通教程中有專門介紹. 問(wèn):用(圖4)進(jìn)行修改線時(shí)拉起時(shí)怎總是往左邊拉起(圖5),不知有什么辦法可以輕易想拉起左就左,右就右。答: 具體條件不明,請(qǐng)檢查一下您的DESIGN GRID,是否太大了. 問(wèn): 好不容易拉起右邊但是用(圖6)修改線怎么改怎么下面都會(huì)有一條不能和在一起,而你教程里都會(huì)好好的(圖8)答:這可能還是與您的GRID 設(shè)置有關(guān),不過(guò)沒(méi)有問(wèn)題,您可以將不需要的那段線刪除.最重要的是需要找到布線的感覺(jué),每個(gè)軟件都不相同,所以需要多練習(xí)。 問(wèn): 尊敬的老師:您好!這個(gè)圖已經(jīng)畫好了,但我只對(duì)(如圖1)一種的完全間距進(jìn)行檢查,怎么錯(cuò)誤就那么多,不知怎么改進(jìn)。請(qǐng)老師指點(diǎn)。這個(gè)圖在附件中請(qǐng)老師幫看一下,如果還有什么問(wèn)題請(qǐng)指出來(lái),本人在改進(jìn)。謝!!!!!答:請(qǐng)注意您的DRC SETUP窗口下的設(shè)置是錯(cuò)誤的,現(xiàn)在選中的SAME NET是對(duì)相同NET進(jìn)行檢查,應(yīng)該選擇NET TO ALL.而不是SAME NET有關(guān)各項(xiàng)參數(shù)的含義請(qǐng)仔細(xì)閱讀第5部教程. 問(wèn): U101元件已建好,但元件框的拐角處不知是否正確,請(qǐng)幫忙CHECK 答:元件框等可以通過(guò)修改編輯來(lái)完成。問(wèn): U102和U103元件沒(méi)建完全,在自動(dòng)建元件參數(shù)中有幾個(gè)不明白:如:SOIC--》silk screen欄下spacing from pin與outdent from first pin對(duì)應(yīng)U102和U103元件應(yīng)寫什么數(shù)值,還有這兩個(gè)元件SILK怎么自動(dòng)設(shè)置,以及SILK內(nèi)有個(gè)圓圈怎么才能畫得與該元件參數(shù)一致。 答:Spacing from pin指從PIN到SILK的Y方向的距離,outdent from first pin是第一PIN與SILK端點(diǎn)間的距離.請(qǐng)根據(jù)元件資料自己計(jì)算。
