Modify the cdf parameters of the diode

Hi All,

I have a problem while trying to change the cdf parameters of the diode
whose main cdf parameters are: "area", "l", "w", and "m"

1.Default behaviour:
When I enter the "l" and "w" parameters in the schematic the "area" is calculated automatically.

2. Behaviour after modifying base CDF:
when I modify the cdf parameters of the diode such that the "area" is editable while "l" and "w" are not editable, and try to enter any "area" value in the schematic it isn't accepted and returns to the default value immedietly

So could you please help me to enter the area value instead of l and w?

Thanks

It appears that your diode device defines a callback to automatically compute area based on l and w. You would like to instead enter an area value and have l and/or w computed automatically. This likely requires modifying the callbacks as your device does not appear to currently support this mode. Not only do you need to make area editable you must update the callbacks.

Hi lorenz,

Thanks for your reply,
and I'd be grateful if you guided me how to edit these callbacks.

Best regards,
Islam

Hi Islam,

If you are not the owner of the library I'd recommend to contact the owner about modifying the device.

To modify the device we would need to consider the device CDF including callbacks and also the model. In your case I don't know what library or model you are using. Your model may take l and w as input. In that case do you want a square device? Do you want to have a fixed l and calculate w based on the area?
