How to get the coordinates of all instances in the layout hierarchy ?

Marben,

procedure(CCFgetInstanceNamesAndCoords(master @optional (transform list(0:0 "R0" 1)) (hierInstPath "/"))
  foreach(inst master~>instances
    printf("%s%s %L\n" hierInstPath inst~>name dbTransformPoint(inst~>xy transform))
    CCFgetInstanceNamesAndCoords(
      inst~>master
      dbConcatTransform(inst~>transform transform)
      strcat(hierInstPath inst~>name "/")
    )
  )
  t
)

Or something similar.

Regards,

Andrew.

Hi Andrew,

Thank you very much for the prompt reply. 

The coordinates are correct. 

But how can I get all the cellname of the instances in the hierarchy to display with their coordinates ? 

because the output is like these : 

/|I37/|I0/|I0/|M2 (449.205 213.005)
/|I37/|I0/|I0/|M1 (449.205 214.145)
/|I37/|I0/|I0/|M4 (449.205 210.725)

I want the output is just like these : 

 /|vref003c/|vref003b5/|vref003b5/||M2 (449.205 210.725)

 /|vref003c/|vref003b5/|vref003b5/||M1 (449.205 210.725) 

 /|vref003c/|vref003b5/|vref003b5/||M4 (449.205 210.725)

Please help. 

Best regards,

Marben

Marben:

Change:

      strcat(hierInstPath inst~>name "/")

to:

      strcat(hierInstPath inst~>cellName "/")

Hi Andrew,

The code is now working exactly as I wanted. 

 I got now the cellnames in all the hierarchy displaying with their coordinates.

Thank you very much !!!

Hi Andrew , 

I used the code and test my layout , for serval insts is OK , for large layout , it has  the message

*Error*   dbConcatTransform:   Invalid  transform  -   nil

How to  fix it ?

Thank you.

Charley,

This will happen if you have mosaics. I neglected to include a check in the code:

procedure(CCFgetInstanceNamesAndCoords(master @optional (transform list(0:0 "R0" 1)) (hierInstPath "/"))
  foreach(inst master~>instances
    when(inst~>objType=="inst"
      printf("%s%s %L\n" hierInstPath inst~>name dbTransformPoint(inst~>xy transform))
      CCFgetInstanceNamesAndCoords(
        inst~>master
        dbConcatTransform(inst~>transform transform)
        strcat(hierInstPath inst~>name "/")
      )
    )
  )
  t
)

The code above should run, but will ignore mosaics.

Regards,

Andrew.

Hi Andrew , 

This code is helpful , Could you help to consider mosaic not ignore ?

Thank you,

Charley 

Charley,

Rather than writing it (I don't really have the bandwidth to do that today), I'll just give you some pointers:

• You can iterate over cv~>mosaics to get all the mosaics and you can get the bBox of each.
• If you have mosaics of cells which have hierarchy underneath, you may want to expand all the sub-instances to give you the effective coordinates of each sub-instance. That gets a bit more complicated, but you could use code similar to that in this recent post to handle all the transformations in a mosaic (the code there handles IC5141 and IC61 because mosaics are represented differently in CDB and OA). You could borrow the mosaic handling part and adapt the recursive call in that.

Regards,

Andrew.
