Leveraging Baseline Checks for Robust Reliability Verification

As IP and IC designers and verification teams tackle increased complexity and expectations, reliability verification has become a necessary ingredient for success. Automotive, always-on mobile devices, IOT and other platforms require increasingly lower power envelopes and reduced device leakage while maintaining overall device performance. Foundries have also created new process nodes targeted for these applications. Having the ability to establish baseline checks for design and reliability requirements is critical to first pass success. January 08, 2018
