我實驗室是使用.18um 1p3m的製程。 學長今天出了一道問題給我,8 n1 D+ _) C/ D& V# u: Q$ A# |
要我寫一個command file去把layout裡的vdd全抓出來,方便他檢查! u# r; u2 Z3 ^/ t9 t
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1 {1 I) S/ ~2 h
寫的command file後只會出現metal1、metal2及metal3。 " T8 U$ Q5 Z) s, T8 D! @ X- h8 h' 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: z2 I+ B2 ]6 F# H
command file呢?希望能給小妹一點意見,或者有無相關data能參考...。 ( H: a, ^7 g: f" \$ f7 J9 H6 P0 ?8 J v) d l) f

妳最好註明是哪個軟體用的Command file。這樣別人比較好幫妳..作者: camilla 時間: 2009-8-19 12:17 AM
