RF-Microwave Circuits/Simulation Tools

Xpedion GoldenGate includes advanced RF and microwave simulators- RFlinear, RF non-linear harmonic balance with Krylov sub-space and envelope transient withnon-linear phase noise. Seamlessly integrated into widely used Affirma Analog Artist EDA environment, GoldenGate is complementary to Spectre RF and significantlyreduces design-cycles and design-time for wireless integrated circuits and products.

Today's wireless design teams require accurate and fast RF, microwaveand transient simulators to handle large and complex RFdesigns. There are stringent specifications for non-linearity, distortion, gain compression, harmonics, efficiency, phase noise and spurious mixing products. Circuits operate in highly non-linear and deep saturation regimes with digital modulated input signals. Also, RFintegrated circuits are tightly integrated with low frequency analog, DSPand digital designs. This requires the RFdesign environment to be tightly integrated with main stream EDA tools, to reduce the number of design iterations and design-cycle time. Xpedion GoldenGate is designed to meet the needs of wireless integrated circuit designers working in both defense and commercial wireless communications. It offers a set of the most sophisticated RF, microwave and envelope transient simulators combined with a unified set of accurate model libraries, complementary to Spectre RF. Simulators are optimized to handle today's 2G and 2.5G, evolving 3G,Bluetooth RF integrated circuits and complex modulation schemes. Users can perform multiple analyses, such as DC,multi-tone RF, and phase noise, all on a single schematic, while using various modulation sources.
