Could you please let me know, how I can get the bBox value of a selected metal?

Ie, it should display the bBox value in the CIW window of virtuoso cadence. 

Like for example, the below code will display the x and y coordinates of a selected instance in the CIW window. 

procedure( getxy()

let( ()

coordList = nil

foreach(item geGetSelSet()

printf("Selected item coordinate: %L\n" item~>xy)

coordList = cons(item~>xy coordList)

)

)

)

But I'm trying to display the bBox values of a selected metal in the CIW window.

Arokia,

This code shows how to print the individual bBoxes or the overall bBoxes:

procedure(CCFshowBBox(@key printIndividual printOverall (figs geGetSelSet()))
  when(figs
    destructuringBind(((ollx olly) (ourx oury)) car(figs)~>bBox
      foreach(fig figs
        when(printIndividual
          printf("Selected item bBox: %L\n" fig~>bBox)
        )
        destructuringBind(((llx lly) (urx ury)) fig~>bBox
          ollx=min(ollx llx)
          olly=min(olly lly)
          ourx=max(ourx urx)
          oury=max(oury ury)
        )
      )
      when(printOverall
        printf("Overall bBox of selected objects: %L\n"
          list(ollx:olly ourx:oury))
      )
      list(ollx:olly ourx:oury)
    )
  )
)

To use it:

CCFshowBBox(?printIndividual t)

CCFshowBBox(?printIndividual t ?printOverall t)

CCFshowBBox(?printOverall t)

depending on what you want. Of course, you may want to adapt as you see fit. What the code does is use destructuringBind to split out the lower left x and y, and upper left x and y, and collect the min and max of these over all items before reassembling into a bBox type list. Note that it slightly unnecessarily visits the first element in the selected set twice, but that was to avoid having an additional printIndividual condition and print outside of the foreach loop.

Hope that helps!

Arokia,

procedure(CCFshowBBox(@key printIndividual printOverall (figs geGetSelSet()))
  when(figs
    destructuringBind(((ollx olly) (ourx oury)) car(figs)~>bBox
      foreach(fig figs
        when(printIndividual
          printf("Selected item bBox: %L\n" fig~>bBox)
        )
        destructuringBind(((llx lly) (urx ury)) fig~>bBox
          ollx=min(ollx llx)
          olly=min(olly lly)
          ourx=max(ourx urx)
          oury=max(oury ury)
        )
      )
      when(printOverall
        printf("Overall bBox of selected objects: %L\n"
          list(ollx:olly ourx:oury))
      )
      list(ollx:olly ourx:oury)
    )
  )
)

To use it:

CCFshowBBox(?printIndividual t)

CCFshowBBox(?printIndividual t ?printOverall t)

CCFshowBBox(?printOverall t)
