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

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

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
2 x% Z6 ^- R/ m6 F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 ,
* J8 B( A! |  G/ J$ c* @% ^" O# X/ C7 P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,
* i* C; l$ r8 k9 J; q" n, A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.
