Hill, California - June 2, 2005.
OEA International, Inc., today announced a 50X performance boost in the
of the resistance portion of a net for its popular NET-AN[TM]
full 3D RCLK parasitic extraction tool of a network. The NET-AN tool, the
fastest and most accurate full 3D extractor in the industry, is now even
faster. With its higher resistance extraction speed, designers can extract
entire power networks on a chip. This is particularly important for
designers who work with advanced Nano-meter technologies where accurate
power simulation is a major concern.
achieved this speed boost through innovative advances in its intelligent
meshing and field solving algorithms. The NET-AN extractor uses a fully
integrated 3D field solver to dynamically extract resistance and
capacitance. In addition, it accurately extracts inductance and mutual
inductance parasitics—an important capability for delay and skew analysis in
high-speed critical nets. Other extraction tools on the market use
approximation and formula-based methodologies that are limited to resistance
and capacitance, and have much wider error margins than the NET-AN tool.
While these less accurate methodologies have a speed advantage over full 3D
field solvers, the speed difference is less of a factor with this new
release of NET-AN.
"OEA's NET-AN tool delivers unmatched speed
and accuracy," said Jerry Tallinger, vice president of sales and
marketing at OEA International. "Our customers, such as SUN Microsystems,
have found that DSM ICs have a greatly increased number of nets which need
the higher accuracy of NET-AN. The improved NET-AN speed allows them
to maintain the level of accuracy required within project schedules."
coupled 3D field solution parasitic extraction.
Multi-net simulations produce capacitively coupled, and optionally
inductively coupled, distributed SPICE sub-circuit models. These models
allow accurate crosstalk and signal integrity simulations.
Single- or multi-net specification. Designers may select and highlight nets for extraction
by annotated name, by using the display and mouse, or by using reference
GDSII cells. Individual nets, lists of nets, or groups of coupled nets may
be specified for extraction. Also, the surrounding net expansion area to be
included in the field simulation is specified.
Full-path SPICE circuits with P&R integration. When a specified path or tree consists of
multiple nets, NET-AN can automatically include the referenced driver,
buffer, and load cell SPICE sub-circuits in the main SPICE output file and
add the appropriate measure statements. The NET-AN results can then be used
in SPICE to calculate accurate delay and skew values in report or SDF
Connectivity based hierarchical graphic interface. OEA's advanced IC graphics tool,
Post-Layout WorkShop, handles reading of standard IC data, display of the
layout, selection of nets, building 3D models, and display of color-coded
displays. It will read and display an entire hierarchical VLSI module from
GDSII, including calculating full connectivity, renaming nets, and assigning
nodes. Levels of hierarchy can be toggled on and off, and the display can
zoom in and out to view as much or as little detail as desired.
Process and device technology definition. Post-Layout WorkShop menus may be used to
define and save the process technology for the design, including metal and
dielectric thickness and metal process bias values. Material properties that
are necessary for accurate extraction, such as dielectric constant and metal
width dependent resistivity, are also defined. NET-AN recognizes IC
devices such as transistors, resistors, and capacitors through flexible
device definition menus, and stores the definitions with the process
and interactive graphics interface. With NET-AN designers may operate in either
a scriptable batch mode or in a fully interactive graphics mode.
International, Inc., is the industry leader in 3D extraction of
interconnects. OEA's tools are currently used in the most demanding
extraction and design environments. Some of the world's most advanced design
facilities use OEA tools for detailed analysis and design of high-speed
clocks, buses, I/O rings, and power grids. For additional information call
