要trace layout上的power line?

camilla

各位前輩,

   我實驗室是使用.18um 1p3m的製程。 學長今天出了一道問題給我,
要我寫一個command file去把layout裡的vdd全抓出來,方便他檢查
  z9 g) P5 E! D% S! q( b我畫的layout,但在有轉層的地方,不要顯示via出來,只希望在執行完我
寫的command file後只會出現metal1、metal2及metal3。
5 C$ y4 C) B$ Z# a7 Y8 Z5 r   但我今天試了很久還是試不出來,不知道有無前輩們是否也寫過類似的
" ~2 {2 ?( F8 H: {" }- r9 ncommand file呢?希望能給小妹一點意見,或者有無相關data能參考...。
- z5 D+ z9 N7 i# ~: D# }" g) T
麻煩各位前輩了~謝謝~

妳最好註明是哪個軟體用的Command file。這樣別人比較好幫妳..
