Emerging Portable Consumer Devices Drive the Need for High Performance Power Management ICs (PMICs)
The features integrated in mobile consumer devices continue to
increase at a rate that far outpaces the development in battery
technology and power delivery. Therefore, the power conversion
methodology and architecture must evolve in such a way to keep the
battery life of mobile devices at a reasonable level.
Application processors are increasingly becoming more complex,
and system engineers are striving to optimize architectures to ensure
the user experience is not damaged by power running out during
user interaction. It is unacceptable for the device to power-down due
to low battery levels during game play; for it to get too hot during
charging; for it to freeze during multi-tasking; or simply for it to be
unable to perform basic tasks due to internal power dissipation issues.
This article explores some of the potential methods of improving
battery lifetime with PMICs in order to improve the user experience.
Solving Verification Issues Facing Semiconductor Companies Pressured to Get Products to Market
In the fast-paced world of consumer electronics, getting a
competitive product to market quickly is the goal. Margins
matter. Quality matters. A product that bombs in the market
due to poor performance or quality can kill a small company and
wound even the largest.
Enhanced features, functionality and performance are driving the
next generation of system-on-chip (SOC) designs that now contain
not just one, but multiple processors enabling almost every possible
form of communication and computation. Verifying that these
devices work as intended is hellish, leaving semiconductor companies
strategizing about how to ensure sufficient product quality without
incurring cost overruns or slowing down time to market. After all, it's
all about making a profit and having a hit.
Often, this challenging burden falls on verification engineers
who must resort to manually developing tests for these big, complex
chips, an insufficient approach for designs with multiple embedded
processors. Fortunately, new, cost-effective approaches in SOC
verification are emerging to automate this process and provide more
thorough verification without impacting time to market.
