Overview
Proteus is unusual among electronics packages because the schematic, the simulator and the board layout are the same design rather than three files that have to be kept in step. Draw a circuit, press play, and it runs. Change a resistor value and the waveform on the virtual oscilloscope changes with it. The netlist that feeds the layout editor comes from the same drawing.
The simulation engine is mixed mode, meaning analogue and digital parts coexist in one circuit rather than needing separate tools. Beyond that, the microcontroller models actually execute compiled firmware. Load a hex file onto a simulated part, and the code runs against simulated peripherals, virtual instruments and animated components, so an LED on the schematic lights when the firmware sets the pin. For teaching and for early prototyping that removes the hardware from the loop entirely.
The layout side carries what a board designer expects: multi-layer routing with design rule checking, an autorouter, copper pour, differential pairs and length matching, a 3D viewer that shows the assembled board with component models, and output of the manufacturing file set along with a bill of materials. The library covers a large part of the common component space and new parts can be built from the package editor.
What it does well
One design, three views
Schematic, simulation and PCB layout all read the same design, so the netlist never drifts out of step with the drawing.
Mixed mode simulation
Analogue and digital parts simulate together in one circuit, with virtual instruments including an oscilloscope, logic analyser and signal generator.
Firmware on simulated silicon
Load compiled firmware onto a simulated microcontroller and watch it drive simulated peripherals and animated components in real time.
PCB layout and routing
Multi-layer boards with design rules, autorouting, copper pour, differential pairs and length matching, checked before output.
3D view and manufacturing output
Inspect the assembled board in three dimensions and export the full manufacturing file set with a bill of materials.

Installation
- Extract the archive to a local folder.
- Remove any earlier Proteus installation before starting setup.
- Run the installer and let the component libraries register, which takes a while.
- Apply the included configuration step before first launch.
- Open a sample design and run the simulation once to confirm the models load.
Before you start
Library registration is the slow part of setup, let it finish rather than assuming it has hung.
Simulation speed depends heavily on the digital section, large logic blocks slow the analogue solver.
Custom parts built in the package editor live in a user library, back that folder up before reinstalling.
Questions about this title
Does firmware really run in the simulation?
Yes, load a compiled hex file onto a simulated part and it executes against the simulated peripherals.
Can it produce manufacturing files?
Yes, the full output set and a bill of materials come from the layout editor.
Is the component library complete?
It covers a large part of the common space, and the package editor builds anything missing.
Does it do multi-layer boards?
Yes, with design rules, copper pour, differential pairs and length matching.
About this listing
This entry was checked on a clean install of Windows 10 / 11 (64-bit) before it was published, and it is rechecked whenever the package is rebuilt. The figures on this page come from the site index rather than from the publisher, so the download count is what people here have actually pulled.
If a mirror stops answering, use the contact form and it gets replaced. Reports about a specific title are handled faster than general messages because they name the file, the mirror and the point at which the transfer stopped.
Requests for a different version, a different language build or an older release go on the requests page. Older versions of a title are usually still held even when only the current one is listed.
