Does it work with the simulator? I tried all the 4-port transistors and
couldn't get any to work. The message box says for most 4-port
transistors:
--
Converting layout in facet xx{sch}, writing VHDL to facet xx{vhdl}
Back-annotation information has been added (library must be saved)
Compiling VHDL in facet xx{vhdl}, writing netlist to facet xx{net-als}
Simulating netlist in facet xx{net-als}
Insufficient parameters declared for model 'NMOSTRAN' in netlist
--
I also tried some 3-port transistors and two-port "VCVS" and such,
but couldn't get any to work. I'd be very delighted if you could tell me
exactly which component is the right one and how to get it to work with
the simulator. Without the simulator I could just as well use Xfig =)

Since I suspect a little it could be a bug with the simulator, I attached
this schematics (as readable dump) in this message. What's wrong with it?
It almost works, but not quite. It works until the input signal changes
the second time (when control signals are ON). Details in documentation
view.

Should I care what Export type I use, Input/Output/Unknown/etc.?

Very surprising since Electric looks wonderful--if I just get around these
few problems. It would be really great. (If I'd get it working well I
would have good reason to "buy" actually it--I'm going to use it for real
paid work if I get it to work).
