Skill code to apply instance orientation to a cordinate

shajujan

Hi,

I'm looking to extract label cordinates of an instance based on how the instance is placed, i.e, after factoring in the orientation of the instance. Has anyone written code like this? For eg. x:y = 10:20 would become -10:20 after MY, 20:10 after MYR90

Thanks,

Shaju

  • You can use dbTransformPoint to transform the point.

  • More specifically:

    xy=10:20
    dbTransformPoint(xy list(0:0 "MY"))
    dbTransformPoint(xy list(0:0 "MXR90"))

  • Thanks Derek. I got it to work.

     procedure( dumpPins( file )
            let( (inst cv fp x pins pin)

            inst = car(geGetSelSet())
            ;Required because I want to open the layout view, if instance is xform
            cv = dbOpenCellViewByType(inst~>master~>libName inst~>master~>cellName "layout")
            if( cv then
                fp = outfile(file)

                pins = setof( x cv~>shapes (x~>objType=="label" && x~>lpp=='("AP" "pin")) )
                foreach( pin pins
                         ;Displacement occurs after mag is applied
                         xy = dbTransformPoint(pin~>xy list(inst~>xy inst~>orient inst~>mag))
                         fprintf( fp "%s\t%f\t%f\n" pin~>theLabel float(round(car(xy))) float(round(cadr(xy))) )
                )
                dbClose(cv)
                close(fp)
                printf( "dumpPins: found %d pins in %L\n" length(pins) cv~>cellName )
            else
                printf( "dumpPins: ERROR: Could not open %s/layout\n" cv~>cellName )
            )
    ))
