how to create pins for(or automatical connect) bulk in layout

acom

Hi all,

we would like to add power pins for (or automaically connect) the bulk of the nmos/pmos by using skill script.

Do you have any clue for these?

We thought flylines can show the bulk's connection.So we guess the skill could recongnize the bulk information.

And we could write skill to automatical connect or showing their connection relationship by creating pins for them .

 But when i created the bulk for nmos/pmos by turing on the"Edit Insance Properties~>Parameter~>Draw body contact(Tub tie)" in virtuoso.

i still could not get the connectivity for the bulk connection infor.Only the S,D,G information.

 

 a=geGetSelectedSet()

a~>terminals~>name

(("D" "S" "G"))

a~>terminals~>net~>name

(("A" "GND" "B"))
