Recently, I'm drawing the inductor in the layout. My procedure to do this is, first drawing a ring, second convert it to polygon. But I find it is not very convenient since after you convert the ring into the polygon the width of the metal can't be changed.
Could someone know how to solve this? Or is there any other better procedure to draw an inductor and transformer?
Thanks in advance~~~
It's still not entirely clear, but I think you really want either a pcell to create the inductor geometries, or one of the various third-party inductor synthesis tools on the market.
You could also place an instance of passiveLib/spiralInd/layout - passiveLib can be added to your cds.lib using:
define passiveLib $(inst_root_with:tools/dfII/bin/virtuoso)/tools/dfII/samples/artist/passiveLib
That said, I don't think this is supported any more - it's not documented these days. I played quickly and couldn't make it work.
