Overview
The Glitch Detector macro comprehensively addresses typical SOC power supply and other voltage glitch monitoring needs in a fully integrated easy-to-use macro. The Glitch Detector macro includes an internal bandgap style voltage reference circuit which is used as a reference to compare the voltage supplies against.
The Glitch Detector macro is fully asynchronous with hot outputs, so requires no clock or other synchronizing signal to work correctly. Only when the monitored voltage inputs have exceeded a user-selected voltage level will the respective Glitch Detector output signal indicate that a violation is detected.
The Glitch Detector outputs a core logic level signal, with a high level representing a glitch or continuous voltage above the selected value, and a low level representing a glitch or continuous voltage below the selected value.

Rising software complexity, tighter development timelines, and cost pressures require automotive companies to re-engineer how they design, deploy, and maintain their system architectures. Addressing these challenges requires an agile, collaborative approach to engineering — from silicon to systems — along with trusted partners capable of delivering powerful, integrated solutions.
Embedded systems have become increasingly important in today's world of automation. Particularly in the field of industrial automation, embedded systems play an important role in speeding up production and controlling factory systems
Digital Power Control Highlights
The fast track development and 24x7 operations have put tremendous pressure on the servers, networking systems and communication equipments. It has become necessary that these systems should operate reliably irrespective of the change in external operating environment like the temperature, humidity, and power fluctuations or, on chip conditions like on-chip temperature, internal voltage levels etc. Measuring the reliability of these physical systems is must for every operational unit.
ISO/SAE 21434 elevates hardware security to a first-class requirement in automotive systems, where physical attacks can undermine secure boot, protected debug, and execution integrity. Among physical fault techniques, near-infrared Laser Fault Injection (LFI) is the most precise lab instrument to expose silicon-level vulnerabilities.
Today, Movellus is announcing Aeonic Insight PDNIQ 2, a bench-to-in-field telemetry platform for datacenter power management that enables SoCs to run at their true power and performance limits across the full bench-to-in-field cycle.
