Multisim is described as 'Is industry-standard SPICE simulation and circuit design software for analog, digital, and power electronics in education and research' and is a circuit simulator in the education & reference category. There are more than 25 alternatives to Multisim for a variety of platforms, including Windows, Linux, Mac, Web-based and iPhone apps. The best Multisim alternative is Circuit JS, which is both free and Open Source. Other great apps like Multisim are QUCS, LTspice, Altium Designer and Proteus PCB design.
This is a javascript electronic circuit simulator. When the applet starts up you will see an animated schematic of a simple LRC circuit. The green color indicates positive voltage. The gray color indicates ground. A red color indicates negative voltage.
The Quite Universal Circuit Simulator (QUCS) is an integrated circuit simulator allowing the simulation and graphical presentation of results of large-signal, small-signal and noise behavior in circuits.
LTspice IV is a high performance Spice III simulator, schematic capture and waveform viewer with enhancements and models for easing the simulation of switching regulators.
Features a unified workflow for schematic capture, PCB layout, mixed analog/digital simulation, signal integrity analysis, real-time 3D editing, ECAD-MCAD collaboration, component libraries, collaborative design tools, BOM generation, routing, and manufacturing outputs.
Proteus PCB design combines the schematic capture and ARES PCB layout programs to provide a powerful, integrated and easy to use suite of tools for professional PCB Design.

Its a good basic tool, but once doing anything past the pure basics its falls short really fast.
