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..

4 c; F9 i2 M+ }. F; y8 g# f• layer
A required original layer or layer set, or a derived polygon layer.
1 P! Z6 q; h& ?! w' o* v- t• name
A required name of a net, which can contain one or more question mark (?) characters. The
# s. x7 }. X! Z2 t? is a wildcard character that matches zero or more characters. You can specify name any
number of times in one statement. The name can be a string variable (see Variable).
Description
Selects all layer polygons that belong to the net having the specified name. To avoid ambiguity,
you must use the parameters in layer name order.

3 n, j. \# t8 L8 G8 l6 gDo not use this operation to obtain net shorting information. The Net operation uses net

  \7 P' B2 ~% `) Lshorted nets, it assumes it has found a single net, and assigns it one name.
The connectivity on layer must be established through a connectivity operation.
