Google AI ModeSep 15, 2026
My pick: LTspice for simulation; KiCad if you're designing the actual board too.
Choosing the right circuit simulation software depends heavily on what kind of project you are building (analog, digital, power electronics, or microcontroller-based) and whether you prefer an offline desktop tool or a quick browser-based sandbox.
Here is a breakdown of the best options available, categorized by use case:
LTspice — Best for Analog & Mixed-Signal SPICE Simulation. It is a legendary, industry-standard, and completely free offline simulator backed by Analog Devices. It handles massive circuits with complex non-linear analog behaviors, switching regulators, and filters exceptionally well. It's fast and reliable, though the user interface feels a bit dated.KiCad — Best Open-Source All-in-One (Schematic + PCB + Simulation). If your project is moving past the simulation phase straight into making a physical Printed Circuit Board, KiCad is phenomenal. It features integrated SPICE simulation capabilities alongside professional-grade schematic capture and PCB layout tools.Tinkercad Circuits — Best for Beginners & Arduino Projects. If your project involves an Arduino, ESP32, or basic sensors and LEDs, Tinkercad lets you wire up a virtual breadboard and write/test C++ code directly in your browser.
EasyEDA — Best Cloud-Based Collaboration Tool. EasyEDA runs right in your web browser or via a desktop app. It combines schematic capture, mixed-mode circuit simulation, and seamless transition to ordering custom PCB layouts, making it great if you want zero-install friction.
EveryCircuit — Best for Visualizing Circuit Dynamics. Available as a web and mobile app, EveryCircuit uses stunning real-time visual animations of voltage, current, and charge directly on top of the schematic. It’s fantastic for instantly seeing why a circuit behaves the way it does while tweaking knobs live.
Autodesk Fusion 360 Electronics — Best for Advanced Unified ECAD/MCAD. If your electronics project needs to fit inside a custom 3D mechanical enclosure, Fusion 360 integrates schematic capture, simulation, and true 3D PCB layout into a single workspace.To help narrow down the best fit, tell me:
Yes. The right choice depends heavily on what you're building, but these are the main options I'd consider in 2026:
LTspice — excellent for analog circuits, power supplies, amplifiers, filters, MOSFETs, op-amps, and transient analysis. It's free and supports real SPICE models.KiCad — a strong choice if the project will become a real PCB. Its schematic editor integrates ngspice, so you can simulate the same design you're preparing for PCB layout.Falstad Circuit Simulator — great for quickly experimenting and understanding how circuits behave. It's browser-based and visually shows current and voltage, but it's not a substitute for detailed SPICE simulation.If you're building something that you'll actually manufacture as a PCB, KiCad is a very practical starting point.
If you're primarily designing and analyzing an analog/power circuit, I'd start with LTspice.
If you tell me what your project is (e.g. audio amplifier, battery charger, motor controller, ESP32 device, RF circuit, power supply, sensor circuit), I can narrow it down to 1–2 tools and explain exactly why.
Choosing the right circuit simulation software depends entirely on what you are building—whether it's analog power electronics, digital logic, or a microcontroller-based gadget.
Here are the top options broken down by use case:
LTspice: The gold standard for analog and mixed-signal simulation. It is entirely free, incredibly fast, industry-standard, and handles heavy-duty power electronics and transient analysis with ease.QSPICE: A modern, high-performance SPICE simulator designed by longtime industry veterans. It features ultra-fast simulation speeds and modern UI, making it a great alternative if you want bleeding-edge SPICE performance.Falstad Circuit: A brilliant, lightweight, and completely free browser-based interactive simulator. It visualizes current, voltage, and charge flow in real-time animation, making it unmatched for quick conceptual testing and learning.Tinkercad Circuits: Perfect if your project involves an Arduino or basic breadboard wiring. It lets you simulate code execution alongside virtual components right in your web browser.
CircuitLab: A clean, professional browser-based schematic editor and simulator that doesn't require any local installation, ideal for quick sharing and clean documentation.KiCad (with Ngspice): If you plan to transition from simulation to a physical printed circuit board (PCB), KiCad is a powerful, open-source PCB suite with native SPICE integration built right into the workflow.To help narrow down the best fit, tell me:
