I already use LTspice for simulation. Why should I use Signal Chain Designer?
Signal Chain Designer is intended to be used earlier in the design flow for fast part selection and quick circuit exploration. You can export your design directly to LTspice from within the Signal Chain Designer Tool to continue with further verification in LTspice.
