The Impact of UCIe on Chiplet Design: Lowering Barriers and Driving Innovation
by Kalar Rajendiran on 08-15-2024 at 6:00 am

Comparative Analysis of Chiplet Interconnect Standards (Physical Layer)

The semiconductor industry is experiencing a significant transformation with the advent of chiplet design, a modular approach that breaks down complex chips into smaller, functional blocks called chiplets. A chiplet-based design approach offers numerous advantages, such as improved performance, reduced development … Read More


The Future of Logic Equivalence Checking

The Future of Logic Equivalence Checking
by Bernard Murphy on 08-07-2024 at 6:00 am

LEC concept

Logic equivalence checking (LEC) is an automated process to verify that modified versions of a design evolving through implementation remain logically equivalent to the functionally signed-off RTL. This becomes important when accounting for retiming optimizations and for necessary implementation-stage ECOs which must… Read More

by Bernard Murphy on 05-29-2024 at 6:00 am

Innovation New

We have talked about fault localization (root cause analysis) in several reviews. This early-release paper looks at applying LLM technology to the task. Paul Cunningham (GM, Verification at Cadence), Raúl Camposano (Silicon Catalyst, entrepreneur, former Synopsys CTO and now Silvaco CTO) and I continue our series on research… Read More


A Recipe for Performance Optimization in Arm-Based Systems

A Recipe for Performance Optimization in Arm-Based Systems
by Bernard Murphy on 05-16-2024 at 6:00 am

Performance cookbook for Arm min (1)

Around the mid-2000’s the performance component of Moore’s Law started to tail off. That slack was nicely picked up by architecture improvements which continue to march forward but add a new layer of complexity in performance optimization and verification. Nick Heaton (Distinguished Engineer and Verification Architect at… Read More
