// Warning:
// The scaling with HICUMm and HICUMarea is done here from model to here variables in order to save memory.
// Classical spice scaling with "area" is implemented, but it is not recommended to be used. If you want
// scaling, more sophisticated expressions should be used. Those can be found in modern PDKs or should be
// provided by modeling engineers.
// For discrete devices, the multiplication facotor "m" should give reasonable results.
//
// The HICUMm device multiplicaton factor can be exected to give good results.

// IT : qp0 ~ (area m)**2 qp0 ~ area m icbar ~ area m
// BE junction: cjei0 ~ area m cjep0 ~ m
// ibeis ~ area m ibeps ~ m
// cbepar ~ m -> area scaling not reasonable
// BC junction: cjci0 ~ area m cjcx0 ~ m

// ireis ~ area m ireps ~ m
// cbcpar ~ m -> area scaling not reasonable
