Implementing Robust Watchdog Timers for Embedded Systems

Watchdogs are essential system design components that reset systems for recovery. Originally standalone timer ASICs, they're now integrated into power management devices, voltage supervisors, and microcontrollers to enhance functional safety. This article explains various watchdog timers, their interactions, and design strategies for multiple watchdogs, particularly in functionally safe multicore systems requiring independence.

Tackling Low-Voltage Signaling in Inverter Design: Part 1

Often, low voltage signaling issues are silent during the initial evaluation phase of product development, and once the power is turned up suddenly, communication stops being reliable. By identifying key analysis steps at each stage of the design process, this two-part article will help you plan, identify, and solve these issues.

Introduction to Validation Test Concepts in a Mixed Signal ASIC

Traditionally, validation engineers of analog products have had to worry about one thing, their analog function. But with the advent of functional safety, the complexity in system design has increased, and functions once found only in digital devices are now making their way into analog devices as well. This leaves individuals with one question- how to validate?
