*Error* dbTransformPoint: Invalid point - nil

Reinice

Hi All,

I want to get the points of a terminal(a "polygon" object type) pins(e.g. PLUS-MINUS, E-B-C) from a schematic symbol

Here is my script:

foreach( cell ddGetObj("QCBGB7_09T")~>cells

cvId=dbOpenCellViewByType("QCBGB7_09T" cell~>name "schematic" "schematic" "a")

foreach(inst cvId~>instances

if(inst~>cellName=="ndio" then

when(inst~>purpose == "cell"

foreach(insTerm inst~>insTerms

insTermPntsO=car(insTerm~>terms~>pins~>fig~>points)

ll=nth(0 insTermPntsO)

ur=nth(2 insTermPntsO)

tform=inst~>transform

;;transform ll=lower right and ur=upper right points of a symbol

insTermPntLL=dbTransformPoint(ll tform)

insTermPntUR=dbTransformPoint(ur tform)

);end of foreach

);end of when

);end of if

);end of foreach

);end of foreach

I' am having this error everytime I run this script for the "ndio" schematic symbol. By the way "ndio" is a symbol_xform(symbol pcell)

*Error* dbTransformPoint: Invalid point - nil

But if I use the script first time for other symbol such as pnp, for once I 'am not encountering this error. By the way "pnp" is also a symbol_xform(symbol pcell)

After I run the script again for pnp I' am encountering the same error.

Please correct the wrong part of my script.

Can anyone help me. It will be highly appreciated if anyone can help.

Thank You Very Much in advance.

Thanks and Regards,

Reinice

  • Hi Marcel,

    Yup, your right the inst~>xy does the job. I' am getting the origin of my instance schematic. It's just a flow issue on my real code. Thanks. = )

    Hi Andrew,

    On the starting code that you gave to me before(forum #1313594)

    1. Is there a way to make placement of new instance(new process) in the center and not depending on pinOrigin from the config.file?

    2. How can I modify the code for me to migrate also other cellview other than the curent open cellview without opening them all?

    When I migrate old instance that have connection to wire on the edge of it's terminal box, it is left hang and not connected when replaced by the new instance. 

    3. How can I wire the new instance(new process) in the middle on each of it's terminal if it's counter part old instance(old process) was wired on the edge on each of it's terminal box?

    Thank you very much in advance.
