calibre lvs的user-defined device的問題?

linjeffrey

Dear 先進們,
# F2 f' X! I. [. v, }* R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?
, _1 K+ M4 Y, f/ S2 k  i+ c' L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......)?
% h! a9 n  J6 r. ~# Y1 t$ D====================================================================================================
DEVICE NCH5ISO isongat poly(G) bndiff(S) bndiff(D) isopsub(B) nxwell(B1) netlist model NCH5ISO netlist element "X" [
" S& O# a3 U" u/ g! o3 f8 h/ h1 N7 Z   property W,L
   W=(perimeter_coincide(isongat, bndiff ) + perimeter_inside(isongat, bndiff)) / 2

]

看過 SVRF 後 ,好像DEVICE 沒有辦法描述5個PIN的 元件喔
