multiple IO row issue

Hi All,

 I want to use multiple IO rows to place inline IO pads. The first row is bond pads, and the second row is IO pads. I typed commands below

setIoRowMargin E 1 0
setIoRowMargin S 1 0
setIoRowMargin W 1 0
setIoRowMargin N 1 0

setIoRowMargin E 2 100
setIoRowMargin S 2 100
setIoRowMargin W 2 100
setIoRowMargin N 2 100

placePadIO -rows 2

And in my IO arrangement file, I wrote something like (... just for reducing the longth of the post)

(globals
    version = 3
    io_order = default
)
 

(iopad
    (topleft
   
    (inst    name="TOPLEFTCORNER"    cell="PCORNER_25" place_status=placed)
    )
   
    (topright
   
    (inst    name="TOPRIGHTCORNER_A"    cell="PCORNER_25" place_status=placed)
    )
   
    (bottomleft
   
    (inst    name="BOTTOMLEFTCORNER"    cell="PCORNER_25" place_status=placed)
    )
   
    (bottomright
   
    (inst    name="BOTTOMRIGHTCORNER"    cell="PCORNER_25" place_status=placed)
    )

    (top

        (locals ring_number=1)
        (inst  name="BPIN_port_in_7"    cell="PAD60L" place_status=placed )
        (inst  name="BPIN_port_in_8"    cell="PAD60L" place_status=placed )   
         ...

        (locals ring_number=2)
        (inst  name="IOIN_port_in_7"    place_status=placed )
        ...
                              
    )                         
                              
    (right
       
            (locals ring_number=1)
        (inst  name="BPOUT_acc_out_9"    cell="PAD60L" place_status=placed )   
       ...

        (locals ring_number=2)
        (inst  name="IOOUT_acc_out_9"    place_status=placed )   
        (inst  name="IOOUT_acc_out_8"    place_status=placed )   
        ....
       
    )

  (bottom

        (locals ring_number=1)
        (inst  name="VDDPST_BP_CDG"    cell="PAD60L"     place_status=placed )
        (inst  name="VDDPST_BP_POC"    cell="PAD60L"    place_status=placed )
        ....

        (locals ring_number=2)
        (inst  name="VDDPST_IO_CDG"         place_status=placed )
        ....
  )

  (left

        (locals ring_number=1)

        (inst  name="VDD_BP_1"    cell="PAD60L"      place_status=placed )
        ....

    (locals ring_number=2)
        (inst  name="VDD_IO_1"         place_status=placed )
        (inst  name="VDD_IO_2"        place_status=placed )   
      ....
  )

I thought I could have bond pad ring placed outside IO pad ring. But I always got that IO pad ring is further away from the core compared to bond pad, even I change the margin distance in setIoRowMargin to minus values.

Any help will be appreciated
