Tool directory
Explore Tersa EDA tools for schematic editing, SPICE-compatible simulation, S-parameter analysis, Smith charts, RF measurements, and component tuning.
Move from schematic capture into simulation, RF measurements, Smith chart inspection, and component tuning without splitting the experiment across disconnected tools.
Start with the circuit, then move to the result that helps you make a decision. Tersa keeps schematic editing, simulation and RF inspection in one focused workspace.
Open an S1P or S2P file to inspect magnitude, phase and reflection on a Smith chart. File processing stays in your browser.
Create circuit schematics, run SPICE-compatible analysis, inspect S-parameters and Smith charts, and tune component values across tablet and desktop.
Build and simulate analog and RF circuits on iPhone, iPad and Android with Tersa. Run DC, AC and transient analyses, inspect plots and tune component values.
Inspect S11, S21, S12, S22, return loss, insertion loss, stability, gain, and marker-driven RF measurements in Tersa EDA.
Online Smith chart: plot impedance, calculate VSWR and return loss, and find ideal L/C matching networks at one frequency. Free, no account.
Move between matching theory, a practical Tersa workflow, S-parameter analysis, and Smith chart inspection.
