要trace layout上的power line?

camilla

各位前輩,

- J/ i# z! e6 p  I6 V   我實驗室是使用.18um 1p3m的製程。 學長今天出了一道問題給我,
; }% v4 M6 E9 y要我寫一個command file去把layout裡的vdd全抓出來,方便他檢查
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
* O1 u5 t% O3 v9 p* d% p寫的command file後只會出現metal1、metal2及metal3。
   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
command file呢?希望能給小妹一點意見,或者有無相關data能參考...。

妳最好註明是哪個軟體用的Command file。這樣別人比較好幫妳..

# [1 C- g- R8 k7 [$ ^. A) zA required name of a net, which can contain one or more question mark (?) characters. The
