Hill, California - December 13, 2004. OEA International, Inc. announces new
update to its popular SPIRAL[TM], a 3D inductor design toolset for synthesizing
embedded inductors in analog and RF chips. The new version of SPIRAL adds
enhanced synthesis to minimize inductor footprint size on the chip, faster
capacitance solver for unparalleled performance in solving inductor
simulations, on-line electro-migration rule checking, enhanced process
variation simulation, and full Linux platform support. SPIRAL also adds many
usability options like enhanced S-Parameter, Smith, and 3D viewing,
graphical technology rules file checking, and automatic simulation stop
frequency detection. While SPIRAL simulation was already the number one
choice for advanced inductor design, these enhancements demonstrate OEA's
commitment to delivering the most powerful and fastest design tools for the
most difficult and specialized applications.
Summary of New SPIRAL Features:
As part
of the Automatic Synthesis algorithm, users now have the option of
requesting SPIRAL to find the minimum size footprint to meet their design
needs. This option can be used for simple 2-port inductors or complex
3-port baluns.
A new
capacitance solver has been incorporated which speeds simulation times by as
much as 10X. SPIRAL, which was already the fastest 3D inductor simulator,
now completes the extraction portion of the simulation in just seconds.
A big
concern of RF designers is whether the inductor design meets EM requirements
specified by the foundry. SPIRAL now automatically can check for EM
violating structures before going through a lengthy simulation. SPIRAL
checks the defined structure against foundry rules and prevents the
simulation of violating structures.
Using
foundry process variations, SPIRAL can predict the best case and worst case
performance parameters which can be expected from the design. This unique
capability assures that the inductor design will not adversely affect yield
of the overall design.
OEA has
enhanced the Linux Support with a port compatible with all current Red Hat
Linux versions.
SPIRAL
Tool Overview
By
providing a simple set of performance and physical specifications SPIRAL
allows designers to automatically and quickly synthesize, analyze, and
optimize a wide range of inductors, including baluns, differential inductors
and transformers. In a matter of minutes SPIRAL can find and synthesize an
inductor optimally suited to the users' specific circuit requirements.
SPIRAL can be used in a batch mode, in an interactive mode through a robust
graphical users interface, or seamlessly from within the Cadence DFII
environment SPIRAL generates all of the user modeling needs including GDS2
layout; S-Parameters; Y-Parameters; Z-Parameters; plots of inductance,
resistance and quality factor versus frequency; and narrow-band and
wide-band compact spice models. SPIRAL results have proven to be highly
accurate for mainstream and advanced process proven through validation.
Pricing and Availability
Spiral is
available immediately on Linux and Solaris based systems starting at $25,000
for a time-based license.
