Detail Route 後出現 violation 如何解? 我試過 "Search & Repair" 很多次但也都解
不了 ....

most of them are DRC error.

after sizing up the die size, they will disappear . but this is not my requirement.
i will try to modify routing option too, thanks

感謝版主大大提醒 ~~ 我改了一個 routing option 就 pass Detail route 了 ~~

不知版主大大的 Route Common Options 設定為何?

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.

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 ,
3 z# L% g5 Z* x6 ^7 E" i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,
9 p3 V. ^! K% E" m; e( C有哪位大大知道要如何 fix routing violation ?

然後去點選一閃一閃的錯誤地方,點選後看面板看它顯示是什麼錯誤

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?

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
8 Z% I: c" H1 s4 g/ T/ P問題,再檢查看看吧!!!
