WINNETRIE / ELECTRONICS WORKBENCH

Circuit Studio.

Build a schematic, choose a simulation and read the connected instruments. All measurements are simulated, not physical hardware readings.

Tools & components

Choose a component

Choose a component and click the grid. Wire all required pins; switches toggle in Select mode, potentiometers adjust in Properties. Use Draw wire to connect terminals or branch off existing wires. A closed circuit with a two-pin supply does not need a GND symbol.

Mouse controls & wire help

Left drag on empty grid: select components and wires with a box. Drag selection: move items together. Middle drag: pan. Ctrl+wheel: zoom. Shift: add to selection.

Wire mode: click one terminal, choose 90° waypoints on the grid, then click the destination terminal. Space changes bend direction. In Select mode, click a single straight wire section and press Delete to cut only that section; the remaining open ends get amber connection dots. Drag a section sideways to reroute it. Use a selection box to select complete wires as a group. Escape cancels drawing.

Advanced one-shot analyses

Optional: calculate a single DC operating point, a fixed transient window, or sinusoidal AC RMS values. Run/Stop above is for interactive simulation.

Example loaded. Run an analysis to see simulated readings.

AC RMS and Sweep use the frequency selected here for all sinusoidal sources. Transient uses each source's own frequency in Properties.

Connect a meter to your circuit. Measurement functions are available in its panel.

Analysis graph & waveform exports

General voltage probe: in Select mode, click any terminal. This plot also shows frequency sweeps. Scope channels CH1–CH4 share a common reference (GND) and can display together.

Simulation limitations

Supported: basic DC; RC transients; linear sinusoidal AC R/L/C; ideal voltmeters and ammeters; up to four oscilloscope channels using one scope and a common ground reference, with trigger and scale controls; passive-network resistance / continuity; isolated LED forward-voltage approximation; educational BJT/MOSFET switching models in DC/transient; op-amp/comparator DC and RC-transient models with supply-rail clipping and linear small-signal AC gain-bandwidth behavior; current-aware LED illumination; self-contained SVG/PNG export; GND-optional closed two-pin supply circuits, single-pin positive/negative DC rails with internally shared GND returns; SPST/SPDT switches, NO/NC pushbuttons, 3-pin potentiometers, ideal current sources, simplified diode/zener models in DC/transient. Scope readings are numerical simulations, not actual sampled signals.

Not simulated: 555 models; BJT/MOSFET AC small-signal models; detailed op-amp slew rate, output current limiting, stability and saturation recovery; nonlinear AC diode/zener models; inductor transients. An LED has only a simplified DC approximation; a buzzer acts as a resistive load. Switches use idealized contact resistances.

Do not use simulation alone for electrical or component safety decisions.
