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 ....
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?

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 ,
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,
