Description: National Instruments Multisim now features microcontroller unit co-simulation capabilities, enabling the inclusion of a microcontroller, programmed in assembly or C code, within SPICE-modeled circuits. The MCU functionality in Multisim allows students, educators, and professional users to program MCUs in assembly or C language within the familiar Multisim environment. The MCU capability can be utilized with any of Multisim's virtual instruments for complete system simulation, incorporating the microcontroller and all connected analog and digital SPICE components. The MCU Module supports Intel®/Atmel® 8051/8052 and Microchip PIC16F84A chips, along with a wide range of advanced peripherals like external RAM and ROM, keypads, graphical and alphanumeric LCDs, and others. The MCU Module leverages the Multisim educational platform, making it ideal for courses in digital electronics, computer architecture, MCU programming, embedded control, senior design, and more. The attached archive contains all necessary files to complete this tutorial. This tutorial demonstrates how to create an MCU Module project from scratch, excluding source files. The MCU project featured in this tutorial utilizes a PIC16F84 from Microchip to illustrate a simple up and down counter. Port A of the microcontroller is configured for input and connected to two switches, while Port B is set up as output and linked to a 7-segment display. The switches control the display's activation and alter the counting direction. The 7-segment display indicates the current counter value (0-F). This MCU Module example comprises two identical projects: one built with assembly and the other with C code. The following components are required to complete the circuit as illustrated. All components can be utilized with their default settings. To view the default settings, right-click on any component and select properties. An MCU Module workspace can contain multiple projects that may consist of assembly or C code source files. To repeat the outlined steps, designate the project "C Code Project" as the active MCU project.
The integration of microcontroller units (MCUs) within the National Instruments Multisim environment enhances the simulation capabilities for both educational and professional applications. This feature allows users to seamlessly incorporate MCUs into their circuit designs, facilitating a comprehensive understanding of embedded systems and digital electronics. The support for popular microcontroller architectures, such as the Intel®/Atmel® 8051/8052 and Microchip PIC16F84A, broadens the scope for users to experiment with a variety of applications and peripherals.
In the context of the provided tutorial, the project exemplifies a fundamental application of the PIC16F84A microcontroller, demonstrating its functionality through a simple counter mechanism. The configuration of Port A as an input interface connected to two switches allows for user interaction, while Port B's output configuration to a 7-segment display provides a visual representation of the counting process. This setup not only illustrates basic input/output operations but also serves as a platform for students to learn about programming techniques in both assembly and C languages.
The MCU Module's design supports a modular approach, where multiple projects can coexist within a single workspace, allowing for comparative analysis between different programming methodologies. The ability to switch between assembly and C code projects further enriches the learning experience, enabling users to appreciate the nuances and efficiencies of each programming paradigm. The detailed instructions provided in the tutorial ensure that users can replicate the project effectively, fostering hands-on learning and practical skills in microcontroller programming and circuit design.National Instruments Multisim now has microcontroller unit co-simulation capabilities, allowing you to include a microcontroller, programmed in assembly or C code, within your SPICE modeled circuit.
