Incorrect newly added CDF default value of instantiated instance

nosaj

I added a CDF to device pfet called vb which is calculated by callback of l and w.  vb default value = 0

The pfet that were already instantiated have vb set to 0 independent of l and w value.

How do I force the instantiated instance to calculate vb based on l & w automatically?

I have a way to trigger the callback of l or w to fix correct the vb value but I prefer not to edit the existing schematics.

vb info :

Default Value : 0 

Store Default : yes

Parse as CEL : yes

Editable Condition : nil

Parse as Number : yes

Units : don't use

  • Is the parameter going to just be used in a model? Could you create your model as a subckt model and compute vb in the subckt itself?

    Otherwise I think you'll probably need to trigger the callbacks - not sure what else you could do. 

    Overall, I don't know that the intention of this vb parameter is - if you'd explained that (does it need to be displayed to the user, or is it just for simulation purposes) then perhaps I could suggest an alternative.

  • The question was regarding how to correct the instantiated instance's vb value.
    vb is a newly added CDF and its value calculated is based on l and w.
    All the instantiated instance have vb = 0 instead of being calculated by its callback.
  • In that case you’ll have to trigger the callbacks on each instance, using the methods I described before.
