NI Multisim Microcontroller Functionality: Feature Chart


NI Multisim microcontroller(MCU) functionality (formerly known as the NI Multisim MCU Module) allows you to seamlessly place, program and co-simulate a microcontroller with SPICE in a single environment.

As a part of the Electronics Education platform, the MCU provides an ideal environment for students to learn how a microcontroller works in digital electronics, computer architecture and other design applications. The MCU functionality also offers a convenient way in which to interface an MCU within an analog and digital circuit to emulate the behavior of an entire system.
