International, Inc. (OEA) today announced major update to its P-GRID
3.0[TM], an advanced tool for the analysis of complex IC core power
distribution networks for excessive voltage drop (IR Drop) and
electromigration violations. In 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.
P-GRID features are:
More than 10X speed
improvement, allowing accurate analysis of larger chips.
More compact and
efficient data model for handling via arrays accurately while saving
New color-coded report
outputs detailing block currents, outputs detailing average current in by
area in the contact layer, and details on voltage drop in the via layers.
using this tool, redesigns due to poor power distribution can be prevented
and reliability of the chip power supply improved," said Mike Xie,
Engineering Manager at OEA International.
In 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 II" 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
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. P-GRID will simulate the average IC block
power net, solving in excess of 50 million equations, in just minutes.
was first announced in 1993, and was the first power network distribution
tool available on the market.
Availability and Pricing
software runs on major operating systems, including Sun Solaris, HP-UX, and
Red Hat Linux. OEA's P-GRID Power Network Planning tool is available
immediately starting at $36,000 for a one-year license.
