How to get a value of object in contraint groups?

Hi I'm mingoo.

I would like to know how to get the 'value' property of an object in the contraint group in cellView in CIW.
When accessing an object in the contraint group, I can access properties such as cellView, objType, and defName, but the value property is nil.
I have confirmed that the value is included in the oa file.
Even in C++ using the oa library, I can get a value through the getValue() function, but only in CIW, the value is nil.
I would be grateful if you could tell me how to access the value.

example)

cv = dbOpenCellViewByType( libName cellName viewName)
println(cv~>constraintGroups~>objects~>value)
-> (nil nil nil nil nil nil)

    There are a bunch of constraint groups added for internal usage - is this a constraint group added in the Process Rule Editor in the constraint manager? If so, I would expect the objects to have values. Can you see the constraint groups in the process rule editor with "Design" chosen in the "Process Rules on" setting at the top?

    Otherwise, what are these constraint groups you're trying to look at?

    Regards,

    Andrew

    Thanks to reply.

    I didn't add constraint group in the Process Rules Editor in the constraint manager but using C++ API in oa library.

    Data in constraint group is not actually regard with constraint group.

    I just wanted to use constraint group's structure.

    In this situation, is there no way to get value?

    Please contact customer support - we'd at least need to see the data to understand whether arbitrary (non-Cadence generated) OA constraint group data can be seen by the SKILL constraint infrastructure; it might need an API to access it, but I'm not sure without seeing the data.
