OEA International Announces First Hierarchical Design Planner for Power Distribution Networks
Morgan Hill, CA - May 20, 2002 -
OEA today announced P-PLAN 2.0, an
advanced tool for the planning of core power network distribution rails
on hierarchical chip designs to help avoid IR drop problems and provide
balancing of the current to IO pins.
New features are: hierarchical placement, multiple nets combined in
the same simulation, more accurate rail placement, automatic rail
hook-ups, and flip-chip support. "By using this tool, redesigns due
to poor power distribution can be prevented and reliability of the chip
power supply improved,"said Ersed Akcasu, President of OEA
P-PLAN provides a fast
method to perform tradeoff analysis on core routing rail widths and
spacing. An input file
contains top-level rails and IO rings, block rails and currents, and
voltage source locations. P-PLAN uses this file to create a 3D model file
and voltage and current source inputs for the OEA P-GRID 3D Power
Distribution Network Solver. P-GRID,
with the 3D "Cheetah II" field solver, 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. The user can easily
modify the P-PLAN input and rerun the simulation.
was announced in 1993, and was the first power network distribution tool.
OEA 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.
