The Challenge Of RISC-V Compliance


The open-source RISC-V instruction set architecture (ISA) continues to gain momentum, but the flexibility of RISC-V creates a problem—how do you know if a RISC-V implementation fits basic standards and can play well with other implementations so they all can run the same ecosystem? In addition, how do you ensure that ecosystem development works for all implementations and that all cores that ... » read more

Can Debug Be Tamed?


Debug consumes more time than any other aspect of the chip design and verification process, and it adds uncertainty and risk to semiconductor development because there are always lingering questions about whether enough bugs were caught in the allotted amount of time. Recent figures suggest that the problem is getting worse, too, as complexity and demand for reliability continue to rise. The... » read more

Reverse Debug


Chun Chan, product applications engineering director at Synopsys, talks with Semiconductor Engineering about testbench debug and how adding time markers can speed time to signoff. https://youtu.be/tx_89M1bq3Q » read more

A Simplified Way to Debug IIP Designs and SoC


Design problems that appear in the late phases of the development cycle can be extremely difficult to track down and debug, thus putting project schedules at risk. It's not uncommon for an engineer to run the verification test on what appears to be the main design problem, only to find the problem in the dump. Traditional debug techniques don't always help to localize the issue. This whitepaper... » read more

Taming Concurrency


Concurrency adds complexity for which the industry lacks appropriate tools, and the problem has grown to the point where errors can creep into designs with no easy or consistent way to detect them. In the past, when chips were essentially a single pipeline, this wasn't a problem. In fact, the early pioneers of EDA created a suitable language to describe and contain the necessary concurrency ... » read more

Debug Tops Verification Tasks


Verification engineers are spending an increased percentage of their time in debug — 44%, according to a recent survey by the Wilson Research Group. There are a variety or reasons for this, including the fact that some SoCs are composed of hundreds of internally developed and externally purchased IP blocks and subsystems. New system architectures contribute to the mix, some of which are be... » read more

ATE Lab To Fab


Shu Li, business development manager at Advantest, zeroes in on the communication gap between engineers on the design side and the manufacturing/test side, why it exists, and what needs to be done to bridge that gap in order to speed up and improve test quality. https://youtu.be/Nd-5_twbJBw     See other tech talk videos here » read more

Planning Out Verification


OneSpin Solutions’ Nicolae Tusinschi talks with Semiconductor Engineering about how to move from specification to signoff in a verification flow. https://youtu.be/2zrgaq2I1SQ » read more

When Bugs Escape


Bugs are a fact of life, and they always have been. But verification methodologies may not have evolved fast enough to keep up with the growing size and complexity of systems. The types of bugs are changing, too. Some people call these corner cases. Others call them outliers. Still another group refers to them as simulation-resistance superbugs. In markets such as automotive, the notion o... » read more

Design Verification Is All About Good Hygiene


Design verification has a lot in common with human hygiene practices. The goal of both activities is to remove all dirt, grime, and bugs through an active process of establishing good hygiene. If this process is not followed properly, the result is viruses, infections, and other illnesses. Good verification hygiene is as important in semiconductor development as human hygiene is for a healthy b... » read more
