'''[[RF.Spice A/D]]''' is the outcome of evolution of EMAG Technologies' older EDA tool, '''[[B2.Spice A/D]]''', which was originally developed by Beige Bag Software Inc. in mid nineties. For nearly two decades, B2.Spice has been productively used by thousands of electronic engineers, system designers, students, hobbyists, government agencies, etc. across the globe. [[RF.Spice A/D]] has been built upon the solid and age-tested foundation of [[B2.Spice A/D]] with an emphasis on maintaining its versatility and ease of use. [[RF.Spice A/D]] continues to offer the schematic, simulation and data visualization tools and utilities of the older product including its extensive parts database, its powerful device editor and all the analog, digital and mixed-mode analysis capabilities. To these we have now added a wide variety of transmission line models, multiport RF devices, a greatly expanded network analysis capability and a large library of system-level "black-box" virtual blocks for waveform generation, analog and digital signal processing, spectral operations and popular modulation schemes.
== RF.Spice A/D vs. B2.Spice A/D ==
[[RF.Spice A/D]] is now an extensive superset of [[B2.Spice A/D]], offering additional RF simulation capability plus a comprehensive library of system-level black-box virtual blocks. Due to popular demand, EMAG Technologies Inc. continues to offer [[B2.Spice A/D]] simply as the '''"Lite Version"''' of the [[RF.Spice A/D]] product. The [[User Interface|user interface]] of the two products are now identical and both share the same documentation including the tutorial lessons. However, the users of the [[B2.Spice A/D]] edition will find some [[menus]] greyed out. Needless to say, the parts database of the [[B2.Spice A/D]] edition is a subset of the parts database of [[RF.Spice A/D]].
== The Stages of a Circuit/System Simulation ==
You can run both of [[RF.Spice]]'s mixed-mode and [[Digital Simulation|digital simulation]] engines in either of its two simulation modes, that is, either as a live simulation or as a predefined test. However, digital circuit analysis is more effective as a live simulation, whereby you can step time by the clock cycles and observe your circuit's response using live digital timing diagrams. On the other hand, for most RF circuits you need to perform either an AC frequency sweep test or a network analysis.
