One of the hallmark features of the 14.3 build is the seamless integration with external microcontroller unit (MCU) architectures. Users can write, compile, and debug assembly or C code for microcontrollers (like the PIC16F84A or 8051) directly within the simulation environment. The "143" update fixed several synchronization bugs present in 14.2, ensuring that digital I/O toggling in code matched real-time SPICE timesteps.
NI Multisim 14.3 (often written as 14.3) is the current stable release of National Instruments’ industry-standard SPICE simulation software. Released in April 2022, this version focuses on enhancing the bridge between educational theory and professional circuit design. ni-multisim-143
