From schematic to measured response

Tersa EDA keeps the circuit, analysis setup, measurements, and tuning controls in one flow so an experiment can move from an idea to a useful plot without changing tools.

Create or open the circuit schematic
Choose AC, transient, or RF analysis
Inspect waveforms, markers, and derived measurements
Tune values and compare the response

A focused RF and analog workspace

Tersa EDA is intentionally described as a lightweight RF and analog tuning notebook rather than a full ADS, AWR, KiCad, or LTspice replacement.

FAQ

Is Tersa EDA only an online circuit simulator?

No. It combines ECAD schematic editing, simulation setup, RF measurement views, plots, and component tuning.

Is it intended for beginners?

The interface is approachable, but the measurements and workflow are aimed at practical RF and analog circuit work.
