Question asked by luciano.artuso on Aug 1, 2017

      Hello,

 

I need to extract these parameters from all cells present on gds file:

 

placement rotation , x placement coordinate , y placement coordinate  and bbox.

 

For the first 3 information, I haven't problem, but  how ca I get bbox in my following script?

 

Many thanks in advance and regards
