Skill Code for rotation

mraghu

I'm a longtime user of Virtuoso for CAD layout but never had to do any Skill programming before. Recenly I've started working on designs that need rotation (from 10 to 170 degrees, in steps of 10 degree), and each rotation would need to be saved to a separate gds file. These are the steps I wish to perform

* select all (all shapes in the layout)

* rotate by x degree, with the center being (0,0)

*  output to stream file <streamname>-x.gds

I'm wondering if Skill programming would make it easier to do this? If so, would anyone give me pointers on which functions to call?

Thanks,

  • Hi Austin CAD guy,

    Thanks for the pointers. I'm on IC6.1, and luckliy my device is small and already flattened. We run the CAD through electron beam lithography - so no masks needed. But the software we use for lithography only allows for 90 degree rotations. So I'm forced to rotate in the CAD software itself.

     I will try out the  dbTransformCellView. Thanks!
