Engineering & Scientific Software - System Simulators
Manufacturers & Services

 - RF CafeSystem simulators listed here apply primarily to those used for analog, RF, and microwave circuits. Designing high frequency systems for first-pass success requires a very high level of sophistication by the software. It must contain system models that accurately compute values that take into account component and subsystem level parameters like noise figure, intercept points, over-the-air links, gain, intermodulation products, etc. Generally, price correlates directly to the capability of the software.
