*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 Derek,

    Thanks for the info on how to know attributes.

    "~>terms" is just a typo. The real code has "~>term"

    I' am now able to get the "points" of a pin on an instance(schematic).

    Hi Andrew,

    Remember my previous post about migrating from old process to new process(where you gave a starting point)? This current post is related to that.

    Please refer to the original post(this post). In my current code I replaced inst~>master(of "ndio") by masterId of the new process:

    masterId = dbOpenCellViewByType("gpdk40" "ndio" "symbol" "schematicSymbol")

    My question is how can I get the origin of this instance in the schematic whose master(old process) has been replaced by another masterId(new process). I 'am using inst~>xy but I 'am not getting the right origin(xy).

    Thank you very much in advance.

    Thanks and Regards,
