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

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) i6 Q4 k! S3 ^1 s5 L
layout 的缺點都是只看結果有錯,卻不知log 中就有告訴你有2 H2 E/ O( m) X& v/ C
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 ,  f) h9 P/ }4 X: t
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,

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.

thanks for you

most of them are DRC error.7 |' \1 M3 m/ j- Y; D
