Click on the oscilloscope to move cursors A/B.
Each example builds the complete circuit, starts it and shows a note with what to look for.
Select a block and place it on the canvas.
For linear RLC circuits. Uses the first AC/function source as the excitation. Select a probe or output component before opening Bode.
DC Sweep sweeps a source. Parameter Sweep sweeps the value of the selected component. FFT analyses the first oscilloscope channel. Noise estimates the spectral density. .MEAS computes automatic metrics. .STEP 2D sweeps two components at once and runs a real grid of points.
Import/export SPICE decks with recursive .SUBCKT hierarchy, PULSE/PWL, .PARAM, .IC, .NODESET, .TEMP and extended models. You can paste the contents of a manufacturer’s library next to the netlist so its .MODEL/.SUBCKT are resolved locally.
Regression tests of the engine against analytical solutions and a comparison workflow with external LTspice results. Total Engineering doesn’t invent LTspice results: you can import the CSV generated by LTspice to calculate the error directly.
| Test | Reference | Total Engineering | Error | Status |
|---|
Load a CSV with id,value columns using the same IDs as the report (10 IDs: divider, Ohm, diode, RC AC/transient, RL, RLC, BJT, NMOS and op-amp). The error against that external run is calculated.
