VSS-SquareVisual System Simulator™ (VSS) is a complete software suite for today’s complex communication systems that enables engineers to design the right system architecture and formulate suitable specifications for each of the underlying components.

VSS is built upon Unified Data Model™ architecture (as is Microwave Office®) and therefore provides for seamless system and circuit level co-simulation.
