Title: how to change schematic automatically
Post by Julian18 on Dec 9^th, 2007, 6:53pm

Hi, there
I have a heap of pins and wires to be added to my schematics, can I do that automatically using skill code??

thanks.

I would assume so. I know we have skill code that automatically adds a bunch of instances.

Pins should be easy; don't know if adding the wires is hard if you have to position them accurately to connect to the pins. We just name the nets on the terminals of our instances, so we don't need wires.

Hi,
yes you can edit a schematic or layout using SKILL. E.g. PCELLS are also SKILL based. Please refer to the document "Virtuoso Schematic Editor SKILL Functions Reference". You will find it inside the DFII install hierarchy (../CDSDIR/doc/...)
To create a wire you can use the following command:
schCreateWire( cv "draw" "full" list(0:0 1:0) 0.0625 0.0625 0.0 )
To create an instance:
symbolId = dbOpenCellViewByType( "test" "inv1" "symbol" "" 'r )
instId = schCreateInst( cvId symbolId "I25" 0:0 "R90" )
