Sorry to randomly jump in here, but in ngspice, the only way to probe current is to probe a 0V voltage source? Theres no other work arounds for this? For example, if I had a very large hierachical design with 10,000 transistors in it and I wanted to plot the drain current of one particular transistor, I'd have to either edit the schematics and break apart the net and insert a 0V voltage source or hack the netlist? Isnt that a pretty important missing feautre? Gnucap lets you probe device currents without hacking the schematics.
