Movellus Announces Industry-First Integrated Droop Response System for SoCs

Sunnyvale, California, June 13th, 2023 6:00AM PDT (Global Newswire) – Movellus, today announced an industry-first integrated droop response system. This innovative solution is designed to simultaneously address the challenges of voltage droop and enable fine-grained DVFS capability, which in combination can significantly reduce the power consumption of complex integrated circuits while increasing operational reliability. In addition to detecting and responding to voltage droops, the solution incorporates extensive monitoring and observability features that will provide valuable insight to modern silicon health and lifecycle management systems.

The AWM2 system adaptation time is amongst the fastest in the industry – similar in performance to full custom solutions but offered as off-the-shelf synthesizable IP. This can result in power saving of more than 10%, making it ideal for complex, power-sensitive SoCs.

“The true power of our digital IP platform is demonstrated in our new droop response system,” said Mo Faisal, CEO of Movellus, “We added autonomous, programmable behavior to our adaptive clocking solution, inserted observability functionality for silicon health and analytics, and developed a cohesive droop response solution that can be delivered as off the shelf IP.”

The integrated droop response system combines droop detection and compensation into a complete integrated system, reducing effort while still gaining maximum benefit. The system’s observability also provides design engineers greater visibility into SoC performance, enabling them to make informed decisions and apply optimal silicon life cycle management strategies.

“In today’s fiercely competitive IC markets, improvements in power efficiency and performance can be a difference-maker,” said Dave Fick, co-founder and CEO at Mythic. “Movellus’ Droop Response System squeezes improvements from the voltage and frequency guardbands that we typically take for granted. Finding these hidden savings and making them easy to deploy is why Movellus is such a great partner to work with.”

“In the age of many high-performance processors on an SOC, the old rules of thumb about activity factors no longer apply. Even if you have TDP headroom, regulators and on-chip power delivery may not be able to keep up with 1000+ processors all going from idle to full-blast computation,” said Darren Jones, vice president of VLSI engineering at Esperanto Technologies. “Hardware designers need tools and solutions to solve transient supply droop. The traditional solution is to over-design, operate at a higher voltage, and even lower performance to protect against catastrophic circuit failures. With better tools to identify and better solutions to mitigate transient supply droop, we can operate with higher performance and lower power.”

Key features of the integrated droop response system IP include:

  • Extremely fast time to adapt (detect + respond) for droop with fine-grained clock speed selection
  • Extremely fast response time for DVFS control
  • Industry first observable droop response system for silicon health and analytics management
  • Multi-threshold droop detection
  • Support for remote and local droop detection
  • APB and JTAG interfaces for silicon health and analytics management during bringup, at production test, and during in field operation
