Overview
Analog
FastSPICE uses Berkeley Design Automation’s proprietary Precision Circuit
Analysis™ technology to
deliver true SPICE accuracy,
5X to 10X performance, 5x-10x higher capacity than any other tool.
It is ideal
for any transient simulation that requires true SPICE accuracy and
would take multiple hours or longer in a traditional SPICE simulator –
including post-layout designs with up to 1 million or more elements.
Analog
FastSPICE has been proven on a wide range of production circuits
including full 802.11 a/b/g transceivers, sigma-delta ADCs, automatic
gain control circuits with bandgap and bias, high-speed I/Os, memories
and memory interfaces, and multi-GHz PLLs and DLLs.

Technology
Analog
FastSPICE is based on Precision
Circuit Analysis technology.
This technology is a proprietary combination of innovative applied
mathematics and optimized numerical analysis. Among the core components
are a fast sparse matrix solver, globally convergent nonlinear solvers,
and efficient stiff differential algebraic equation solver. Unlike
digital fastSPICE simulators, Analog
FastSPICE makes no simplifying
assumptions or approximations. It solves the original device equations
on the original circuit with accuracy that is equivalent to, and
may even exceed, traditional SPICE simulators. This means that it needs
no block-level tuning and always provides true accuracy at every node
in the circuit; hence every simulation is a full performance
simulation. The result is breakthrough technology that can address a
whole new class of verification problems.
Fast,
Robust DC Analysis
Analog
FastSPICE includes an innovative,
globally convergent solvers that provide unprecedented dc analysis
speed and reliability.
Co-Simulation
with Leading Verilog Simulators
Analog FastSPICE Co-Simulation provides design teams an unprecedented
combination of true SPICE accuracy, 5x-10x higher performance, and
5x-10x higher capacity – all using an industry standard flow.
Analog FastSPICE Co-Simulation uses a standard Cadence® Analog
Design Environment based flow, supports standard “Spectre®-Verilog”
use model, includes mixed-analog/digital debugging,
and integrates with industry leading Verilog simulators including
Cadence NC-Verilog®, Cadence Verilog-XL, and Mentor®
ModelSim®.
Fits Your Existing Flow
Analog
FastSPICE easily fits into existing HSPICE® and Spectre-based
verification flows. It reads standard HSPICE and Spectre-format
netlists and supports popular device model formats, including BSIM3,
BSIM4, Gummel-Poon, MOS11, and Mextram.
Analog
FastSPICE runs in both batch mode and
interactive mode using the Cadence Virtuoso Analog Design Environment.
Results can be viewed with BDA’s waveform viewer, WaveCrave, or third
party waveform viewers such as those from Cadence and Synopsys®.
