身為IC設計者，我面對的最大壓力？

chip123

8月中旬有兩天整以「如何搭起設計除錯與結果分析之間的橋樑？」為主題的IC設計研討會，如果部分會員們有意參加，在那之前何妨先來討論討論如何？

引言回覆:
IC 設計的大小與複雜度，對於產出良率與產品上市時間影響甚鉅。設計者除了要面對更為嚴苛的設計工作之外，還必須同時承受時間上的壓力。

即使運用現有的分析工具，在設計除錯與結果分析之間，還是隱約存在一道看不見的鴻溝。就算是針對 Spice 模擬工具的需求，將解決方案與看起來 “還算不錯” 的波形分析結合在一起，依舊不能有效消弭這段差距。完美整合的 “最頂級” 解決方案，不僅使用容易，更可支援以下三類資料的分析作業：模型建立（Modeling）過程中所描述之模擬、硬體量測，以及系統階層。

壓力有部份來自EDA跟不上製程進化的腳步
  [! k" g7 u) C$ A更新EDA太貴,只好冒險用舊版的EDA TOOL
或是Gate-count太大,擔心目前的EDA無法勝任最佳化的任務
' P$ n, G. H5 e例如 90n 的製程 到底要搭配啥版本的Synthesis和Layout tools?
  m. a9 u% t( E5 z3 A$ C9 j$ x有誰清楚呢?

ryanchen

這個問題還真的不是三言兩語就可以說完
; G- |. Y( f, T7 O
其實與其說是壓力, 還不如說設計上遇到的核心問題是如何讓模擬的數據更貼近真實的情況
比如說多 channel OPAMP output buffer 如何能保證輸出電壓的一制性?
如果是單純 pre-simulation 看起來是會一樣的
7 Z7 L. Z) H& w3 d6 Y8 g( }# @但如果考慮真實的情況, layout 怎麼 lay 才會 uniform ? 單顆 OP 如何擺 ?
不同 SLOT 又如何保證 uniform?
! p6 u6 X7 P  c$ l或許 EDA tools 看可否加入製程參數的變異係數下去跑, 以類似統計的方式來看大致上會落在哪個區域,
這方面就得 Foundry 是否願意提供這方面的資料了 ( WAT ?)
- i# ^2 F' F& y1 |8 u0 @" m小弟想請教大家一下, 這樣的構想可以實行嗎? 若有的話如何去做呢?

我認識的一家service company還在用Apollo layout 0.13的ic, 超猛的, 根本是靠經驗在做事嘛...

masonchung

太猛了吧
  D, Z. z2 T/ `2 [/ t  kGUC 還是 Fararday?
+ _6 k( P1 C/ cApollo是.25時代的 後來不是改成SE 和ASTRO了嗎?

一家不太有名的公司啦, 名字還是不要亂報好了
astro是apollo的下一版

主要是要克服 高層的腦袋所思維不合理的 Tapeout Deadline吧
一個新製程  居然壓 3個月 做出來
真是虧 董事長想得出來
3個月後 連LAYOUT都還沒開始動工
最後一共DELAY了半年

(20130422 08:25:47)現代人生活忙碌，常常轉個身就忘記剛才要做的事，或者是注意力無法集中。這是因為生活壓力大，或是大腦同時要處理的訊息太多，所以造成短期健忘的現象。短期健忘只要適時紓壓、調整心態情況就會改善，但真正的失智與健忘有怎樣的區別呢？記憶力退化的人，是否也會有罹患失智症的可能性呢？4月28日熟年誌特別邀請天主教失智老人基金會社工主任陳俊佑先生到西門町的Somebody cafe，與您分享如何自行檢測並預防失智，讓您知道失智症是否已經找上您！本次講座規劃限量贈送大腦保健體操ＤＶＤ及照顧者使用手冊，歡迎讀者踴躍參加！
