calibre lvs的user-defined device的問題?

linjeffrey

Dear 先進們,
% @! r# K# g+ A& R' f. B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?
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......)?
====================================================================================================
DEVICE NCH5ISO isongat poly(G) bndiff(S) bndiff(D) isopsub(B) nxwell(B1) netlist model NCH5ISO netlist element "X" [
  X( \+ T8 c  {  z) L/ `   property W,L
   W=(perimeter_coincide(isongat, bndiff ) + perimeter_inside(isongat, bndiff)) / 2
   L=area(isongat) / W

看過 SVRF 後 ,好像DEVICE 沒有辦法描述5個PIN的 元件喔
