Schematic capture, mixed mode circuit simulation and PCB layout in one package, with microcontroller firmware running inside the simulated circuit before any board is made.
Proteus takes a circuit from an idea on a schematic through to a manufacturable board without changing application. You draw the schematic, simulate it to check it behaves, annotate and transfer the netlist to the layout editor, place and route the board, run the design rule check, and produce the manufacturing outputs. Everything stays linked, so a change on the schematic propagates forward rather than leaving you to remember it.
The simulation engine is the part that sets it apart from ordinary layout packages. It is a mixed mode simulator, so analogue and digital parts of the same circuit are solved together rather than in separate tools. You get virtual instruments on screen, an oscilloscope, logic analyser, signal generator, counter timer, spectrum analyser and protocol analysers for the common serial buses, all wired into the schematic exactly like real bench equipment would be.
Microcontroller co simulation is the feature people actually buy it for. Load your compiled firmware into a simulated part and it executes cycle by cycle inside the circuit, driving the simulated peripherals around it. You can single step the code, set breakpoints, watch registers and variables, and see the effect on a simulated display, motor or sensor at the same time. That means a large amount of embedded debugging happens before any hardware exists.
The PCB side is a full layout package. Multi layer boards with controlled trace widths, differential pairs, copper pour with thermal relief, length matching, interactive routing with push and shove, an autorouter for the tedious sections, full design rule checking, a 3D viewer that shows the assembled board with component models, and output of gerbers, drill files, pick and place data and a bill of materials.
Read the whole list before you start. Most of the reports that come into the desk about this title turn out to be a step taken out of order.
| Processor | Intel or AMD, 64 bit, quad core recommended for simulation |
|---|---|
| Memory | 8 GB minimum, 16 GB for large mixed mode circuits |
| Graphics | 2 GB VRAM for the 3D board viewer |
| Storage | 5 GB free |
| Display | 1920 by 1080 or higher, a second monitor helps a great deal |
Component libraries from an earlier major version import but should be checked before you trust a footprint to manufacture.
Keep the application blocked in your firewall. The library update service will try to check the licence state.
