Hill, California - June 2, 2005.
OEA International, Inc. (OEA) today announced a major update to P-GRID[TM],
an advanced tool for the analysis of complex IC core power distribution
networks for excessive voltage drop (IR Drop) and electromigration
violations. A newly developed solver algorithm ("Cheetah-X") uses a
lightning fast and intelligent 3D analysis and solution of the grid
structure yielding an accurate parasitic model and maintaining a detailed
current simulation model of the full power grid structure. On the average
the new release is at least 50X improvement in CPU time. This means that
power grid layouts which used to take 2 days to simulate, can now be
analyzed, modified, and re-analyzed many times within one work day.
today's large SOC devices and advanced ASICs there are major concerns about
the low voltage margins caused by small voltage differentials, the effects
of switched power for large sections of the chip, and real worries about
excessive power leakage in nanometer technologies. P-GRID helps eliminate
those concerns by giving an accurate analysis of the current distribution
through the core of the chip. "This advancement in the P-GRID 3D solver
removes the limits on the size of the power network practical to analyze,"
said Jerry Tallinger, vice president of sales and marketing at OEA
International. "Power grids which were previously too large for any tool on
the market, such as large SoC processor designs, can now be verified with
P-GRID within a day."
The P-GRID features are:
Unparalleled speed and
accuracy allowing accurate IR drop and electromigration analysis of larger
Compact and efficient
data model for handling large power grids faster while maintaining
outputs detailing block currents, outputs detailing average current in by
area in the contact layer, and details on voltage drop in the via layers.
today's high performance VLSI designs, accurate extraction and modeling of
the power and ground distribution network is essential. P-GRID employs a
fully seamless 3D Laplace/Poisson field solution using the fast proprietary
"Cheetah-X" solver to extract distributed current flow model for even the
most complex networks and calculates the current flow from voltage sources
to current sources. Color-coded outputs make it easy to spot errors in
power distribution such as high IR drop or poor distribution to the voltage
inputs. Other 2D and square count based net extraction methods do not
accurately account for the 3D current distribution and current crowding
effects. Also, because the results of other tools extraction may just be a
SPICE deck, it can be difficult or impossible to use because of too many
I/Os or a SPICE deck just too large to be simulated. Thus, results derived
from these 2D tools can be inaccurate or impossible to use.
Availability and Pricing
software runs on major operating systems, including Sun Solaris, HP-UX, and
Linux. OEA's P-GRID Power Network Planning tool is available immediately
starting at $36,000 for a one-year license.
