要trace layout上的power line?

camilla

各位前輩,

" n( T( d& c5 q' `, o' I   我實驗室是使用.18um 1p3m的製程。 學長今天出了一道問題給我,
! k. ?7 n2 h$ X3 |) o7 J: C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
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..

) m) ~9 U% o/ G. v" W  |$ R" H9 cA required original layer or layer set, or a derived polygon layer.
• name
A required name of a net, which can contain one or more question mark (?) characters. The
# Q1 e2 u5 g7 i, y. }6 A1 \? is a wildcard character that matches zero or more characters. You can specify name any

Description
0 U  J( c' L( J. q. vSelects all layer polygons that belong to the net having the specified name. To avoid ambiguity,
you must use the parameters in layer name order.
6 I. m( B" Q# [+ P6 o8 LNote
' l" E2 R! @" y# }( C, ~2 UDo not use this operation to obtain net shorting information. The Net operation uses net
names assigned by the connectivity extractor. If the connectivity extractor encounters

The connectivity on layer must be established through a connectivity operation.
