关于DRC语法

我也認同mjubct的分析。應該是你的tmp1這個layer name並沒有使用在OPERATION block中。你所規範的TEMPORARY-LAYER所有list都必須有定義在OPERATION block中，且不得為Original layer.
- m# L( G7 b, K2 e% _1 e
以下是Cadence 的Dracula Reference on-line document所寫，裡頭就有提到它的使用前題：
＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝
Example
2 t* k$ v. u! C* ]6 k5 ~In this example, in the first line of the Operation block, abc is the name assigned as the result
of the AND operation. In the second line, abc is assigned as the result of the NOT operation.
7 f3 \: T4 `  d) E& @+ A3 b/ S
*INPUT-LAYER
..
TEMPORARY-LAYER = abc, nbc, real
*END

*OPERATION

我猜，可能你看的書漏寫了吧？建議還是以Cadence on-line document為準。Hope this help.

ps.順便提醒你一下，TEMPORARY-LAYER是屬於INPUT-LAYER block的內容，而非DESCRIPTION block的。
