calibre lvs的user-defined device的問題?

linjeffrey

Dear 先進們,
若有一顆mos需要辨認到五支腳位,那lvs的rule-file和spice檔要如何寫?
& _# u- l" ^  ^% r& d/ q若為若如下的做法,calibre還是無法認到這顆mos device(** WARING: BAD DEVICE on layer isongat at loaction......)?
====================================================================================================

; f% g% ?' q- U1 J$ s* H- f   property W,L
   W=(perimeter_coincide(isongat, bndiff ) + perimeter_inside(isongat, bndiff)) / 2
. C( d* q+ I) k' s4 C& v   L=area(isongat) / W
; h0 t3 v' K! S5 J/ d) _; U]
- g9 j+ ~- ^; O& s- B9 R4 Z& A=======================================================================================================
如能回覆, 感激不盡..!!!

看過 SVRF 後 ,好像DEVICE 沒有辦法描述5個PIN的 元件喔

試試看,  我都是這樣寫的
