Version 14.3 · National Instruments · Windows 10 / 11 (64-bit) · ranked #125 in the library
Schematic capture wired directly to a SPICE simulation engine, so a circuit can be drawn, probed and made to fail on the screen before a single component is soldered to a board.
Read the installation section below before you start. The order of the steps matters on this release.
About this release
Overview
Multisim draws a circuit and then runs it. The schematic editor places components from a large parts database and wires them together, and the SPICE engine underneath turns that schematic into equations and solves them. Instead of building a prototype to find out that a bias point is wrong, you place a virtual probe on the node and read the voltage, which is a much faster and cheaper way to be wrong.
The instrument set is what makes it approachable for anyone who has stood at a bench. Rather than reading raw simulation output, you drag a virtual oscilloscope, multimeter, function generator, bode plotter or logic analyser onto the schematic and connect it like real equipment. The traces and readings match what the same instrument would show on the bench, which makes the simulation a genuine teaching and design tool rather than a wall of numbers.
The professional tier covers the analyses a real design needs: DC operating point, transient, AC sweep, noise, Monte Carlo for component tolerance, worst case, and temperature sweeps. It handles analog, digital and mixed signal circuits together, includes a large database of real manufacturer parts with their actual models, and passes a completed design to a board layout tool so the schematic becomes a physical board.
What it does
Feature breakdown
Schematic capture with a large parts database
Place real manufacturer components with their actual SPICE models and wire them into a working circuit.
Interactive virtual instruments
Oscilloscope, multimeter, function generator, bode plotter, logic analyser and more, connected and read like bench equipment.
Full SPICE analysis set
DC, transient, AC sweep, noise, Monte Carlo, worst case and temperature sweep analyses on the drawn circuit.
Mixed signal simulation
Analog, digital and mixed circuits simulated together rather than in separate environments.
Microcontroller and ladder logic
Simulate common microcontrollers and programmable logic alongside the surrounding analog circuit.
Handoff to board layout
Pass a completed and verified schematic to a PCB layout tool with the netlist intact.
Changed in this build
Version 14.3
- Component database expanded with additional current manufacturer parts and models.
- Faster convergence on large mixed signal circuits.
- Improved virtual instrument responsiveness during interactive simulation.
- Better handling of high node count schematics in the capture editor.
- Several analysis dialogs reorganised for clearer parameter entry.
Installation
Follow these in order
- Go offline before starting.
- Extract the archive.
- Disable real time protection.
- Run setup as administrator and complete the install.
- Apply the included licensing configuration when prompted.
- Launch Multisim, confirm it opens without a licensing prompt, then re-enable protection.
Release notes
From whoever packed it
- Do not let the licensing service reach out. Block its outbound access after install.
- The board layout companion installs alongside it if you selected it during setup.
- Custom parts you add live in the user database, which should be backed up separately from the install.
