TopSpice

Multisim ™ software integrates industry standard spice simulation with an interactive schematic environment to instantly visualize and analyze the behavior of electronic circuits. Its intuitive interface helps teachers reinforce circuit theory and improve theory retention throughout the engineering curriculum. By adding powerful circuit simulation and analysis to the design flow, Multisim ™ helps researchers and designers reduce iterations of printed circuit board (PCB) prototypes and save development costs. Multisim ™ for Education is circuit teaching application software for analog, digital and power electronics courses and labs. Multisim ™ provides engineers with the SPICE simulation, analysis and PCB design tools to rapidly iterate on designs and improve prototype performance.

One animated circuit is worth a thousand equations and diagrams. Animations of voltages, currents, and charges are displayed right on top of the schematic, providing great insight into circuit operation. The real-time circuit simulation engine is custom-built for speed and interactivity. Easy one-click simulation, from simple resistors and logic gates to complex transistor-level oscillators and mixed-signal designs. While the simulation is running, you can flip switches, adjust potentiometers, tune LED current limiting resistors, ramp up input voltages, etc. The circuit will immediately respond to your changes, in real time. Mini-waveforms on top of schematic wires look different for digital and analog signals. Constant analog voltages are shown as numbers, digital wires are color-coded. Any pair of time-domain signals may be plotted in the XY mode. The oscilloscope scale and grid ticks are auto-updated to convenient values as the data changes.
