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.
Formerly known as MultiMCU and the Multisim MCU Module, the Multisim MCU functionality includes C language support, intuitive file management and simulation peripherals. The chart below provides details of the functionality of the Multisim MCU functionality.
