Sometimes you have other global things like clocks, busses, … As is now I think power sources have net= attribute and netname will be local within sub circuit. It could be connected to the outside world with an oridany input symbol by connecting it to the local power source. I think this is rather good solution but can't tell for sure there are any problematic side effects. > Scoping of names is tricky, depending on flow. One gotcha in ngspice is that GND is a hard-wired alias for node 0, so you can’t have an isolated ground in a subcircuit unless you name it differently. A warning about the hard wiring would probably be an appropiate. "Warning local net GND is hardwired with global net GND because of harwiring to node 0 in ngspice". > > Are there use cases where it is OK to use refdes= without mangling in > > flattened hierarchical schematic netlist?
