在 Astro 當 Detail Route 後出現 violation 如何解?

hgby2209

Detail Route 後出現 violation 如何解? 我試過 "Search & Repair" 很多次但也都解
不了 ....
. S! u7 J: z: M5 c* n9 P外包的工程師用同樣的 Area 可作完 APR, 我自己作已經放大 size 卻一直卡在 Detail Route
這個 step .....
請問各位前輩當你們遇到此問題時都是怎麼去解的呢?

P&R 時最重要要去看log,或在跑的過程就有show error, 但
layout 的缺點都是只看結果有錯,卻不知log 中就有告訴你有
問題,再檢查看看吧!!!

沒有 congestion 再加上 detail route 之前也都沒 violation 為何在 detail route 時會出現這麼多 violation 呢?

感謝版主大大的回覆 ~~ 版主大大所述我早知道... 且也做過了 ~~ 如此做是知道哪裡 violation & 得知 violation 的 status ,
, _1 o" o' j* |) V我現在想知道的是如何 Fix violation, 由 QueryError 得知的 Infomation , 並無助於如何 fix violation,
) E0 p; ?0 `1 D, W+ E% e7 Y有哪位大大知道要如何 fix routing violation ?

其實我講的用意是在釐清你的VIOLATION是屬於哪類,比如說,如果是ANTENNA ERROR那我才能告訴你如何解 ,如果是DRC ERROR那就要去分析為啥ASTRO認為是DRC ERROR,也許也會是假錯,有時甚至只是NOTCH,那~~~應該只是你ROUTE COMMOM OPTION沒設好,所以你可能要分析一下你的VIOLATION是哪一類.

差別在於

不知版主大大的 Route Common Options 設定為何?

aaaach

thanks for you
i have the some problem, the astro show me that more than 7000 violation
+ D6 }3 g* W* Y6 f4 n: ymost of them are DRC error.
: G3 E8 I( x( Q+ u% S* p  i don't know why there are so much violation and how to fix them.
8 B: D0 c; f7 j! i4 M+ Q& x2 wafter sizing up the die size, they will disappear . but this is not my requirement.
i will try to modify routing option too, thanks
