要我寫一個command file去把layout裡的vdd全抓出來,方便他檢查6 c" ` F9 n* U+ i. j; K4 ?3 F
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0 X! d: Z+ ]. L g+ V
寫的command file後只會出現metal1、metal2及metal3。 0 q9 i$ P7 V. F* P, i0 |( K 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) o j% M( B1 K& p- h) x4 @
command file呢?希望能給小妹一點意見,或者有無相關data能參考...。 9 N k) u, b+ P: m9 L & _& @8 l- w8 c6 M4 W麻煩各位前輩了~謝謝~ 5 L* M; ~/ x& x; d- M9 M4 {作者: veteran 時間: 2009-8-18 10:37 PM
