The PSpice® Systems Option provides designers with a system-level simulation solution for their designs. Designers utilize PSpice simulation programs for accurate analog and mixed-signal simulations supported by a wide range of board-level models. MATLAB and Simulink are a platform for multi-domain simulation and model-based design of dynamic systems The powerful combination enables developers to accelerate their PCB designs in a range of application areas, from automotive to internet of things (IoT) to industrial designs.
PSpice® Systems Option enables co-simulation of electrical and mechanical systems. Designers can simulate their designs using the Cadence® PSpice® analog and mixed-signal simulator, perform MATLAB and Simulink behavioral-level modeling, and utilize all MATLAB post-process analysis, visualization and measurement functions in a single, integrated system design and debug environment. The result is that design and integration problems can be found earlier in the design process to save time and reduce costs. The integration of the PSpice simulator with MATLAB and Simulink provides a complete system level solution for PCB design and implementation.
