LVS : how to disconnect pins

[cadfile]

Hi,

I need to write a LVS rule for an inductor, which is just coiling
metal
with two pins at two ends. When runing LVS, LVS will report these
two terminals are shorted. So, how can I prevent this from
happening? Any advice is appreciated.

Thanks

Cut out the inductor metal with a dmy layer to
a derived layer!

Bernd

This is the Assura syntax!

;; Layer definition section
;; DFII database input laye
layerDefs( "df2"
m8 = layer( "METAL8" type( "drawing" ) )
;; dummy layer generation
inddmy = layer( "INDDMY" type( "drawing" ) )
;; create labels form DFII pins
m8_text = pinText( "METAL8" )
)

;; Inductor derivation
;; seperate single metal AND inductor layer
m8Ind = geomAnd( inddmy m8 )

;; cut out recognition layer from real metal
m8 = geomAndNot( m8 m8Ind )

geomConnect(
buttOrOver( m8Ind m8 )
)

extractDevice(
"indm8"
m8Ind
m8( "PLUS" "MINUS" )
...
)

I forgot the label inside the geomConnect

geomConnect(
label( m8_text m8 )
buttOrOver( m8Ind m8 )
)

Hi, Bernd, Thank you very much for your advice.
