In traditional control logic design, engineers develop embedded code separate from the analog circuitry, but they eventually need to interact at a system level that is difficult to simulate simultaneously. Accurate and complete desktop system simulation is now possible at an early stage of the design process.ĭescription What Is a Multisim and LabVIEW Complete System Simulation?

During this, processing resources are negotiated between both simulation engines in a variable time-step fashion. The digital logic blocks controlling the Multisim design are developed in LabVIEW.Ī simultaneous point-by-point simulation that includes all of the system dynamics between the analog circuitry and the FPGA-based digital control system is performed. Because the high-power analog circuit is developed in Multisim, it benefits from the new SPICE-based power electronics models featured in Multisim 12.0 such as the MOSFET switches and the nonideal RLCs.

It also examines the system simulation of a 3-phase inverter. This tutorial shows you how to use the Multisim and LabVIEW cosimulation feature to achieve closed-loop simulation of transistor-level power electronics as well as implement FPGA-based digital logic used for control. With NI Multisim and NI LabVIEW software, you can implement desktop simulation of your entire analog and digital system before prototyping.
