How to open two layouts, copy them into a third and save

LostInRTN

I'm writing a script that will run automatically using icfb -nograph -replay script.il. I need it to open three layouts, and copy all the contents of two of the layouts into the third, then save it, close and exit.

I was originally going to use (procedure and let's omitted):
      window1 = dbOpenCellViewByType(Dir Name1 "layout" "" "w")
      window2 = dbOpenCellViewByType(Dir Name2 "layout" "" "r")
      geSelectAll()
      geCopySelSet()
      hiSetCurrentWindow(window1)
      mouseAddPt()
      dbClose(window2)
      window3 = dbOpenCellViewByType(Dir Name3 "layout" "" "r")
      geSelectAll()
      geCopySelSet()
      hiSetCurrentWindow(window1)
      mouseAddPt()  ;
      dbClose(window3)
      dbSave(window1)
      dbClose(window1)
However, dbOpenCellViewByType opens it in memory but doesn't open a window, so the geSelectAll() won't work. geOpen() just opens a design, but not a window- should I use hiOpenWindow + geOpen?

Also, the object returned by dbOpenCellViewByType doesn't match what hiSetCurrentWindow wants. And, I'm not sure how to end the geCopySelSet command- it wants a location to put the copied objects and there's no user to click the mouse.

 Thanks for any help

  • Thanks guys for all the quick responses!

    If it makes things any easier, I suppose I don't need to open icfb with -nograph. I just thought it made sense since theres no user interaction, but my only real requirement is that this is done with no user input.

    Additionally, it is not a full layout- it is just one metal layer + vias. It appears to be made of rectangles and polygons only.

    I'll work on both methods and see which gives me the least pain.

    Cheers,
