Detail Route 後出現 violation 如何解? 我試過 "Search & Repair" 很多次但也都解0 O# z2 J" J* Y3 S

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 " ^3 Z, c6 n( d( ^9 s; _3 b. H2 [, i
這個 step .....

P&R 時最重要要去看log,或在跑的過程就有show error, 但
6 v- L3 B0 t' K- g5 n2 j# Elayout 的缺點都是只看結果有錯,卻不知log 中就有告訴你有- |# j* I* K) S5 M, k! x
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 ,
; X( g$ E8 l$ ^5 d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,5 l6 D- t9 s+ D+ Q# c
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.

thanks for you
& U$ `5 @: p5 W) e5 }i have the some problem, the astro show me that more than 7000 violation/ T+ r. X' e4 M) d& a
most of them are DRC error.
8 S% i1 }% X% J+ m2 a% y7 w3 M# b  i don't know why there are so much violation and how to fix them.
  Z% q" [$ Q3 G! l9 mafter sizing up the die size, they will disappear . but this is not my requirement.* M) \. \9 D+ O! m
i will try to modify routing option too, thanks
