Analog analysis modes
For an analog circuit, use Circuit analysis to select a mode. The menu contains DC operating point, AC frequency sweep, Transient step response, SPICE · schematic and SPICE · netlist.
Choose the mode for the calculation you want to inspect, then review the settings in the inspector. Samples with a SPICE analysis preset carry that preset with the circuit.
Digital analysis modes
For a digital circuit, Digital analysis offers Time waveform and Truth table. Choose Time waveform to inspect signal values over time. Choose Truth table to inspect binary input combinations and their output values.
DDS counter schematic opens as a Digital circuit diagram. The other digital samples open as editable Digital circuit documents.
