Extract Choices of Dynamic Property

KGh94

Hello,

I have an instance in a schematic that has two parameters: p_1 and p_2. Both p_1 and p_2 are set using a drop-down menu. I extract the choices using the CDF ID of the instance:

cdf_Id = cdfGetInstCDF(inst_Id)
cdf_Id~>p_1~>choices                   => ("1" "2" "3" "4" "5")
cdf_Id~>p_2~>choices                   => ("10" "20" "30" "40" "50")

Problem: In the schematic, p_2 changes every time p_1 is changed. This change is not reflected in the CDF of the instance.
Example: For p_1 = "1", p_2 is ("30" "40" "50"), for p_1 = "2", p_2 is ("10" "20" "30"), etc.

Is there a way to get the updated change using SKILL? Any hints would be appreciated.

Best regards,
Karam

  • Hi Karam,

    I take it that p_2 is a derived CDF parameter that is implemented in terms of a CDF callback correct?

    The flipside of the coin of these CDF callbacks is that they are form callbacks meaning they are only triggered through the "Edit Properties" and the "Create Instance" form (when you place the instance) but not if you change p_1 in terms of a SKILL expression. So my first guess that you do not change p_2 in terms of the "Edit Properties" form do you?

    regards

    Hello Max,

    Thank you for your reply. Turns out p_2 was a master parameter and the information I needed was in other parameters.

    Thanks Max!

    Best regards,
    Karam
