Thanks Boe. Yes, I 100% agree with you and regret not forcing for the inclusion of actual pins in the cell symbols.
For now, I am using the parameter declarations to get the supply information, but this doesn't track any supply changes.
One of the supplies for custom cells is internally generated & must track the main supply to avoid exceeding breakdown levels (depending on where a cell might be used, the supply can be either VPOS or VNEG). For now I can't simulate realistic power up and power down sequences without using 100% transistor level schematics.
Now, you mentioned "the model to have supply pins."
Since the custom cell symbols do not have actual pins, how can I include extra supply pins in the model and still get things to match?
