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

  • Lawrence is right. How's code won't work, because geSelectAllFig does not work unless the cellView is open in a window (I tested this in case this was some behaviour I was unfamiliar with).

    Actually to copy everything would get reasonably complicated relatively quickly. In addition to iterating over the shapes, you'd want to iterate over instances (missing out any mosaicInsts) and mosaics. In IC61 you'd also need to iterate over boundaries, markers, vias, and a few other object types. 

    So what I would probably do (as this keeps it simple) would be to use dbCreateInst() to create an instance of the cell you want to copy the contents of, and then use dbFlattenInst to flatten it. Then you have the choice of preserving pins and ROD objects during the "copy".
