AWR VSS (Visual System Simulator)
Designing complete RF systems is a complex task where you need to find the right combination of RF components, Antennas, and RF circuits on your PCB. Describing the system with behavior models in combination with reuse of existing detailed RF circuits made with Microwave office MWO is an easy task with VSS. The Visual System Simulator (VSS) is working on the same database model like MWO. Behavior models and detailed circuits are dynamically linked together. To compare i.e. two alternate circuits, it requires just a right mouse click to select the other circuit and re-simulate. The circuit itself is updated automatically.
VSS comes with a time domain and a frequency domain simulator optimized for system design with harmonic balance. To add RF components, just add non-linear models as compiled models (for example .DLL) from the component vendor.
