Multisim: Intuitive Circuit Design With Advanced SPICE Simulation

Multisim™ software combines SPICE simulation and circuit design into an environment optimized to simplify common design tasks, which helps you improve performance, minimize errors, and shorten time to prototype. With a library of 55,000 manufacturer-verified components and seamless integration with the Ultiboard™1 PCB layout tools, you can confidently iterate through design decisions and annotate changes between layout and circuit schematic. Use Multisim™ with Ultiboard™ software to rapidly prototype, build interfacing circuitry, and troubleshoot electronic systems.

NI Ultiboard

Ultiboard is printed circuit board design and layout software that integrates seamlessly with Multisim to accelerate PCB prototype development.

Ultiboard software offers efficient PCB design layout and routing with a customizable environment. You can use its flexible tools to place parts and copper with manual precision to define critical board elements. With its automated functionality, you can quickly complete a design. The advanced spreadsheet view, toolbox, and design wizards help you easily manage, control, and define any board layout. Seamless integration with Multisim software provides simple schematic transfer to PCB, and forward and backward annotation ensures design iteration management. You can easily export industry-standard file formats such as Gerber and DXF to complete the design flow from schematic to layout.

NI AWR Design Environment

The NI AWR Design Environment platform provides RF/microwave engineers with integrated high-frequency circuit, system, and EM simulation technologies and design automation to develop physically-realizable electronics ready for manufacturing. The platform helps designers manage complex integrated-circuit (IC), package, and printed-circuit board (PCB) modeling, simulation, and verification, addressing all aspects of circuit behavior to achieve optimal performance and reliable results for first-pass success.


FlexRIO instruments combine large, user-programmable FPGAs and high-performance analog, digital, and RF I/O to offer the flexibility of custom hardware without the cost of custom design.

Thales Alenia Space Dramatically Cuts Design to Production Times with NI AWR Design Environment

TAS designers chose NI AWR Design Environment™ for the ambitious MIDA (Microwave Integrated Design and Analysis) project because it offers a wide variety of integrated simulation technologies, as well as connections to third-party simulators. TAS successfully developed a complete RF/microwave design flow based on NI AWR software by writing a custom piece of software that links Microwave Office via its comprehensive application-programming interface (API) to TAS PDKs and component libraries. This complete design flow enables designers to integrate real components from their predefined libraries into the actual designs. The design time savings and project reuse has enabled TAS to achieve a dramatic reduction in design-to-production times.

Designing a Solar-Powered, Rechargeable Lantern for Developing Nations

The Koinonia Foundation created a clean, renewable light source to replace fuel-based lanterns used in developing countries, by using the NI Multisim and Ultiboard circuit design environments to design the K-Light, a solar-powered, rechargeable lantern that provides an environmentally friendly, economical, and safe alternative to fuel-based lighting for individuals in developing nations.

Automated Test Bench for High-Resolution Audio Test

DOLPHIN INTEGRATION designed a test bench for an automated high-resolution audio codec that integrates analog-to-digital converters and digital-to-analog multichannel converters, based on NI PXI instruments to multiplex analog signals, generate and acquire analog and digital signals, and control components via I2C bus.

D-VASim: A Software Tool to Simulate and Analyze Genetic Logic Circuits

The TECHNICAL UNIVERSITY OF DENMARK created a software tool for the simulation and analysis of genetic logic circuits to help researchers performing wet lab experiments virtually, because the manual process of wet lab experimentation of genetic logic circuits is time consuming and a challenging task for early-stage researchers with limited experience in the field of biology. They used LabVIEW to develop a user-friendly simulation tool named Dynamic Virtual Analyzer and Simulator (D-VASim), which is the first software tool in the domain of synthetic biology that provides a virtual laboratory environment to perform run-time interactive simulation and analysis of genetic logic circuits.

Furuno Electric Co. Uses NI AWR Design Environment and NI FlexRIO Platform to Develop Weather Radar in 40 Percent Less Time

FURUNO wanted to develop a weather radar with flexibility in the signal processing unit to accommodate various potential design changes and incorporate a way to verify the system-level performance by co-simulating the digital and analog sections. They adopted the NI FlexRIO platform for digital section hardware, using graphical system design methodology to accommodate potential design changes in the software, and taking advantage of the co-simulation capability between AWR Visual System Simulator (VSS) and NI LabVIEW software to realize the system-level simulation of digital and analog sections together.

Rapid OEM Prototyping of Medical, Biotech, and Industrial Devices

Cyth Systems developed a ready-to-use, technically proven signal conditioning circuitry that can rapidly integrate daughterboards and daughterboard kits into the NI Single-Board RIO platform for medical and biotech applications, by taking advantage of the productive, optimized circuit simulation and prototyping environments of NI Multisim and NI Ultiboard to rapidly produce our Circaflex boards with few design iterations.

The NT01 Functional Circuit Tester

Fitech Test&Tooling wanted to design and rapidly build a flexible and modular automated test equipment (ATE) for electronic products that can adapt to different units under test (UUTs) and test procedures. They developed a reconfigurable functional circuit tester (FCT) based on software-defined test architecture because it uses modular hardware and graphical software that allows the creation of various instrumentation and test scenarios. The FCT performs end-of-line testing on printed circuit boards (PCBs) of various form factors and technical specifications.
