Problem with schMove()/dbMoveFig function

Inarma

I am trying to rotate a schematic symbol in place. Or, put another way, I want to just change the orientation of the symbol and not change the location of the symbol.

I have tried the functions below to achieve this but they all seem to translate the symbol to odd places:

  • schMove( car(geGetSelSet()) schCV list( 0.0:0.0 "R90" ) )
  • schMove( car(geGetSelSet()) schCV list( car(geGetSelSet())->xy "R90" ) )
  • dbMoveFig( car(geGetSelSet()) schCV list( 0.0:0.0 "R90" ) )
  • dbMoveFig( car(geGetSelSet()) schCV list( car(geGetSelSet())->xy "R90" ) )

Alternatively I could probably just save the previous origin location and put it back after the move but I wanted to understand what I am missing here. Anyway, thanks for the help!

(Bonus Points: I am trying to get this to work for something that would extract the underlying schematic from any given layout. So if you have any info that may help on this I'd appreciate it.)

    I moved this in to the Custom IC SKILL forum as that's more appropriate.

    It probably depends where where you are rotating about. What you practically have to do is concatenate a transformation which translates the instance to the origin, rotates it, and then translates it back again. The code in this post will probably help as it provides a function that lets you choose where you want to rotate about.
