Simplifying Circuit & System Analysis & Design

RF.Spice A/D™ is a powerful visual simulation environment for analysis and design of analog, digital, RF and mixed-signal circuits and systems. Rather than verifying your circuit designs after the fact using real physical components with expensive laboratory test equipment, RF.Spice A/D allows you to perform accurate and realistic simulations of your circuits without clipping wires or splashing solder. With RF.Spice A/D, creating, modifying and simulating electronic circuits and systems is a quick, easy, even enjoyable, process.

The foundation of RF.Spice A/D has been built upon Berkeley Spice 3F5 and Georgia Tech XSpice simulation engines. The analog and digital circuit solvers have been integrated with an extensive library of RF devices, S-parameter-based multiport networks and a large variety of generic and physical transmission line types and transmission line discontinuity models. Featuring more than 25,000 preloaded devices, the parts database of RF.Spice A/D can easily be expanded by importing an unlimited number of external Netlist models or packaging user’s existing circuits as parameterized subcircuit models.

RF.Spice A/D provides a large collection of functional and behavioral macormodels for waveform generation, analog and digital signal processing, spectral processing and various modulation schemes. You can use these so-called black-box virtual blocks to perform effective system-level simulations without having to deal with the internal details of individual subsystems.

Due to popular demand, EMAG Technologies Inc. continues to offer a “Lite” version of RF.Spice A/D under the product name B2.Spice A/D, which was originally acquired from Beige Bag Software Inc. The “Lite” version does not include the RF and system simulation capabilities of the “Pro” version.

A Brief History of RF.Spice A/D

RF.Spice A/D is the outcome of evolution of EMAG’s older EDA tool, B2.Spice A/D, which was originally developed and introduced to the market by Beige Bag Software Inc. in mid 90s. 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 added a large 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.
