Overview
Analog
FastSPICE (AFS)
is the industry’s leading big
analog/RF circuit
simulator proven to deliver foundry-certified true SPICE accuracy
5x-20x faster than traditional SPICE on circuits with up to 10 million
elements.
Part of the Analog
FastSPICE
unified circuit
verification platform,
AFS
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.

HDL Co-Simulation
with Leading Verilog Simulators
Analog FastSPICE Co-Simulation gives design teams an unprecedented
combination of true SPICE accuracy, 5x-20x higher performance, and
5x-10x higher capacity – all using an industry-standard flow.
Analog FastSPICE Co-Simulation supports the standard SPICE-Verilog use
model, includes mixed-analog/digital debugging, and integrates with
industry-leading PLI 2.0 compliant Verilog simulators.
AFS Multi-Core
The AFS
Multi-Core
capability provides up to an additional 2x or higher performance than
single-threaded Analog FastSPICE when run on up to 4 cores. The
additional performance typically helps large and post-layout circuits.
AFS Multi-Core uses multi-threading technology in device evaluation,
matrix solution, and overall simulator control. AFS Multi-Core always
delivers true SPICE accuracy with no performance tradeoffs.

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.
Fits
Your Existing Flow
Analog
FastSPICE easily fits into
existing SPICE
verification flows. It reads industry-standard SPICE netlists and
supports popular device model formats, including BSIM3,
BSIM4, Gummel-Poon, MOS11, and Mextram.
Analog
FastSPICE runs in either batch mode or in interactive mode with
the leading EDA design environment. Results can be viewed with
BDA’s waveform viewer, WaveCrave™, or with third-party
waveform viewers.
