e/SpectreRF

Information
has gloss	eng: SpectreRF is an option to the Spectre Circuit Simulator from Cadence Design Systems. It adds a series of analyses that are particularly useful for RF circuits to the basic capabililies of Spectre. It is by far the most commonly used simulator for RF integrated circuits. SpectreRF was first released in 1996 and was notable for three reasons. First, it was arguably the first RF simulator in that it was the first to be designed for large bipolar and CMOS RF circuits; it used shooting methods as its base algorithm; and it pioneered the use of Krylov subspace methods. The use of shooting methods gave SpectreRF remarkable robustness and the Krylov methods gave it its break through capacity. Previously such simulators were designed to simulate very small GaAs integrated circuits and hybrids. These simulators were based on harmonic balance and could reliably simulate circuits with tens of transistors whereas SpectreRF could simulate circuits with thousands of transistors.
