Title: Creating schematics automatically with Skill
Post by analocation on Jun 12^th, 2008, 4:47am

Hi,
I would like to convert a Spice net list into a schematic via SKill code. However, I have a problem in connecting transitor terminals, because the command "schCreateWire" requires the explicit coordinates of the terminal to be wired. Is there any command, that returns the coordinates for the bulk, gate , drain and source terminals of a certain transistor or a different command that provides an easy way to connect the terminals?

found it on page 158 in "Virtuoso® Schematic Composer User
Guide":

list_of_points=nil
cv=geGetEditCellView()
foreach( inst cv~>instances
when( inst~>purpose == "cell"
printf( " %L\n" inst~>name )
foreach( instTerm inst~>instTerms
printf( " %L\n" instTerm~>name )
foreach( pin instTerm~>term~>pins
printf( " %L" pin~>name )
if( pin~>fig then
bBox = dbTransformBBox( pin~>fig~>bBox inst~>transform )
a=xCoord(car(bBox)) + (xCoord(cadr(bBox)) -
xCoord(car(bBox)))/2
b=yCoord(car(bBox)) + (yCoord(cadr(bBox)) -
yCoord(car(bBox)))/2
list_of_points=cons(a:b list_of_points)
);if
);foreach
);foreach
);when
);foreach
