Leti innovation stories
The multicore circuits used to power latest-generation computers and tablets are so powerful that they generate dozens of watts of thermal energy. In other words, they get pretty hot!
Docea Power has developed a unique software application capable of evaluating— very early on in the design phase—the thermal behavior of a future circuit. The goal is to help circuit designers turn down the heat while keeping circuit performance high.
The new software will round out
Docea Power’s existing Aceplorer
Leti and List interfaced these software
applications with a virtual multicore circuit
platform to create a unique simulation
environment that creates a detailed
picture of the entire circuit’s thermal
behavior. Designers can leverage these
valuable insights to compare different
use strategies and to develop and test
thermal compensation algorithms,
Perhaps the most crucial point in the
development process was to be able to
guarantee the validity of the new models
and tools. To do this, Leti came up with
a thermal model of a 3D processormemory
circuit. When compared to
silicon-based measurements, the margin
of error for the model was less than 5%.
This early-design-stage approach offers
performance far surpassing that of the
after-the-fact design adjustments that
are currently the norm.
