Verification Scorecard: How Well Is The Industry Doing?


Semiconductor Engineering sat down to discuss how well verification tools and methodologies have been keeping up with demand, with Larry Lapides, vice president of sales for Imperas Software; Mike Thompson, director of engineering for the verification task group at OpenHW; Paul Graykowski, technical marketing manager for Arteris IP; Shantanu Ganguly, vice president of product marketing at Caden... » read more

ML And UVM Share Same Flaws


A number of people must be scratching their heads over what UVM and machine learning (ML) have in common, such that they can be described as having the same flaws. In both cases, it is a flaw of omission in some sense. Let's start with ML, and in particular, object recognition. A decade ago, Alexnet, coupled with GPUs, managed to beat all of the object detection systems that relied on tradit... » read more

High-Level Synthesis For RISC-V


High-quality RISC-V implementations are becoming more numerous, but it is the extensibility of the architecture that is driving a lot of design activity. The challenge is designing and implementing custom processors without having to re-implement them every time at the register transfer level (RTL). There are two types of high-level synthesis (HLS) that need to be considered. The first is ge... » read more

Four Requirements To Improve Chip Design Debug


Debug has always been a painful and unavoidable part of semiconductor design and, despite many technological advances, it remains one of the dominant tasks in chip development. At one time, most bugs were detected and diagnosed on actual devices in the bring-up lab, where both visibility and controllability are severely limited. It is certainly true that debugging the results from pre-silicon t... » read more

Continuing Challenges For Open-Source Verification


Experts at the Table: This is the last part of the series of articles derived from the DVCon panel that discussed Verification in the Era of Open Source. It takes the discussion beyond what happened in the panel and utilizes some of the questions that were posed, but never presented to the panelists due to lack of time. Contributing to the discussion are Ashish Darbari, CEO of Axiomise; Serge L... » read more

Scaling Simulation


Without functional simulation the semiconductor industry would not be where it is today, but some people in the industry contend it hasn't received the attention and research it deserves, causing a stagnation in performance. Others disagree, noting that design sizes have increased by orders of magnitude while design times have shrunk, pointing to simulation remaining a suitable tool for the job... » read more

New Methodologies Create New Opportunities


Experts at the Table: Semiconductor Engineering sat down to discuss what open source verification means today and what it should evolve into, with Jean-Marie Brunet, senior director for the Emulation Division at Siemens EDA; Ashish Darbari, CEO of Axiomise; Simon Davidmann, CEO of Imperas Software; Serge Leef, program manager in the Microsystems Technology Office at DARPA; Tao Liu, staff hardwa... » read more

Verification’s Inflection Point


Functional verification is nearing an inflection point, brought on by rising complexity and the many tentacles that are intermixing it with other disciplines. New abstractions or different ways to approach the problems are needed. Being a verification engineer is no longer enough, except for those whose concerns is block-level verification. Most of the time and effort spent in verification i... » read more

Week In Review: Design, Low Power


Tools, Cloud, IP Valtrix Systems updated its STING design verification tool for RISC-V based CPU and SoC implementations. Version 1.9.0 adds support to verify recent changes to the RISC-V user and privilege specifications, including draft versions of the vector and bit manipulation standard extensions. Preliminary support for the draft version of the RISC-V hypervisor extension has also been a... » read more

Verification Convergence: Problem Definition


A while ago, I had to go to the ER with my friend who suddenly had a numb feeling in his face. He felt okay (and everything else is okay with him), but better be safe than sorry. While the doctor examined him I noticed that before tracing the problem itself, she asked some questions to rule-out a problem she was already familiar with and that can manifest itself in similar ways. Only then, a... » read more
