Techfile techDerivedLayers() class

jumboFiatco

I am wanting to include several derived layers in aCadence 6.1 techfile and here are my quiries

(1) Is there any documentation on this tschfile class? So far all i been able to get (online serach) is a 2006 presentation by Cadence

(2) Can one perform sizing in addition to boolean on layers?

(3) Does the class create actual layers when the boolean is satified and will the derived layer stream out?

 

Thanks,

Henry 

  • 1. In your installation directory
       <install_dir>/doc/ascitechfile/ascitechfile.pdf
       <install_dir>/doc/techfileuser/techfileuser.pdf
       Look for 'techDerivedLayers'.

    2. Yes as a two step operation
       derivedLayerA ( 42 ( physicalLayerA 'and physicalLayerB )
       derivedLayerB ( derivedLayerA 'sizeOperator value )
       Size operator can be 'growHorizontal, 'growVertical,
       'shrinkHorizontal, 'shrinkVertical, 'grow, 'shrink.

    3. As far as I know "no".
