Optimization in UDSM designs by RUBICAD's TopQuality Migration Service
For an increasing
number of wireless applications, higher frequencies, lower supply voltage
levels, and power optimization are becoming necessities in IC design. RUBICAD’s
TopQuality Service team utilizes the LADEE Tool Suite which is designed
to solve different kinds of power problems on the physical layout level.
General
reduction of power consumption
Wireless
applications demand the lowest possible power consumption. This can be
achieved by combining a power analysis tool together with the LADEE Tool
Suite. The results of the analysis tools will be automatically implemented
into the physical design by the LADEE Tool Suite. Such layout changes include
transistor sizes and wire changes for reducing parasitic capacitance in
the wiring. This method is particular useful for high-speed full custom
designs such as datapath and DSP. The method can also be applied inside
an ASIC design flow using synthesis and place & route technology.
Voltage
drop
Voltage drop
is a temporary effect that occurs when a chip operates at peak performance.
The number of gate switches in an area of the chip can be so high that
some supply lines show temporary voltage drops, which can cause functional
errors. Voltage drops can be prevented by either improving the power supply
to this particular chip area or by reducing the power consumption in this
area. The first solution requires the implementation of larger power supply
lines. The second solution can be implemented by reducing the capacitance
of the wiring of the local nets in that area. Both solutions can be easy
implemented using the LADEE Tool Suite in combination with CrossSpeed and
external analysis tools.
Hot Spots
Hot spots
are the consequence of high power consumption in a local area. The primary
effect can be overheating of the device; the long-term effect is fatal
errors caused by metal migration. To prevent hot spots, designers can widen
power metal lines to reduce the local current density or they can reduce
the power consumption in that particular area. Both approaches can be combined
with the LADEE Tool Suite.
All of the
above problems can be solved in a single process using the LADEE Tool Suite,
applied either to new designs made from scratch or in combination with
migrating a design to a different process technology.
