National Instruments, Nasdaq (NATI), has introduced Multisim 11, the latest version of its circuit simulation software, with specialized editions for both hands-on learning and professional circuit design. The easy-to-use Multisim software delivers a graphical approach that abstracts the complexities of traditional circuit simulation, helping educators, students and engineers employ advanced circuit analysis technology. The academic edition of Multisim 11 incorporates specialized teaching features and is complemented by circuits textbooks and courseware. Multisim 11 Professional helps engineers optimize circuit designs, minimize errors and reduce prototype iterations. Multisim 11 Academic simplifies digital circuits teaching by exporting raw VHDL from a programmable logic device (PLD) schematic and guides hands-on electronics experiments with new educator-requested AC single-frequency analysis.
