Multisim Touch permits electronics design and simulation anywhere via an Apple iPad.

Provides accurate, interactive simulation results accessible on mobile devices. Easy-to-learn, touch-optimized environment is paired with an industry-standard SPICE simulation engine for high-fidelity simulation results. Allows rapid experimenting with topologies on an iPad, which then exports to the desktop for further analysis, verification, and printed circuit board layout. Features ionclude interactive circuit simulation and analysis for iPad; AC, DC, and transient simulation modes paired with interactive LEDs, switches, bulbs, potentiometers, and probes to visualize circuit performance; intuitive touch-based design environment; exportable via Dropbox or email.
