Back annotation of design parameters in the schematic (SKILL code).

Atul Dwivedi

Hi there,

I am in want of a simple procedure to set the componet values (eg. w,l of MOS; capacitance value of a cap) in the schematic from a file. The input file may contain the desired component value in the required format.  

Please tell me if this is possible. If yes, please suggest the appropriate APIs to do the same and what all formatted information should the input file store.

Thanks in advance.

Regards,

Atul

    If the ID of your capacitor is "instId" and if you have the schematic open then you can modify its parameters using the code below. Then you just need to read in the values from a file which should be straight forward.

    ;; Select the instance
    geDeselectAll()
    geSelectObject( instId )

    ;; Call the "Edit Object Properties" dialog
    ;; Using this method ensures that callbacks are maintained
    schHiObjectProperty()

    ;; Update the instance properties
    schObjPropForm->w->value = "2u"
    schObjPropForm->l->value = "0.5u"

    ;; Close the form
    hiFormDone(schObjPropForm)

    ;; Unselect the instance
    geDeselectAll()
