yes, the embedded nets seems nice if you only have one Vcc/Vdd and one
GND. But they make life a lot more difficult when you have separate
supply voltages.

"Do not draw power and ground pins. That information will be conveyed
using attributes (see the netattrib document)."

Is this really the recommended way still? I've been designing in a big
commercial ASIC suite (Cadence) this spring and there you never use such
things as embedded nets. IMHO this makes things clearer since you have
full control over your nets.
