Is there a way to mark a unit as "power unit" (I think you mentioned sometime back that this might be required to properly make simulation for multi unit symbols possible while still allowing the power unit to be separate. A power unit would also be a "must be placed unit" but i feel separating these two might add more flexibility.)See definition above. I'm not sure having a "required" keyword is useful. Do you have an example in mind.
There are many parts that not only have power connections but also some control connections that are necessary for the function of the part. A lot of these have the control pins shared between many units so it makes sense to move them to a specialized unit. That unit would then be required but does not fulfill the "this is a power unit" thing. Hence my suggestion for a more general "this unit must be placed" vs. "This unit is optional" field. (The "This is a power unit" thing is not really necessary for ERC. At least not if there is a "this is a required unit" flag. The only reason i suggested that is because you mentioned that it might be required for simulation purposes.)
