I'm setting up a circuit to simulate a RLC filter. As explained here(https://docs.easyeda.com/en/Simulation/Chapter4-Introduction-to-using-a-simulator/index.html#The-ground-node-MUST-NOT-have-a-Voltage-Probe-attached-to-it), my circuit should have a power and/or a signal source.
When I'm in the circuit editor, where do I find the power source so I can add them to my circuit?
- I can't find them in the "Commonly library".
- In the "Library", selecting "Search Engine = EasyEDA", "Type = Spice Symbol" and "Classes = System", I can locate a promising section named "Power Sources / Spice Sources". In it there is a VOLTAGE_SOURCE. When I place it in my circuit, the LTSpice netlist export stops complaining and works. However, when selecting this component, it shows no section "Voltage Source Settings" where I can configure the source.
My question is: where do I find the nice power sources that are exemplified here: https://easyeda.com/editor#mode=sim,id=33ceeaef756d4e4d81aef87c9b9f25ea

Brand new interactions and interfaces. 
Easy to use and quick to get started. 
If you want basic sources that you can configure anyhow you like, including adding LTspice specific parameters that are not available in the right hand panel (but which can be added by editing them directly in the schematic) then use the Voltage_Source and Current_Source from the Spice Library:
(but ignore the Description referring to Ngspice: I will try to get that changed to reference the LTspice Help documentation.)
