FPGA Equivalence Checking For A Nuclear Safety Controller


Every chip development team wants to find and fix all the bugs they possibly can in pre-silicon verification. Turning a chip to fix issues found in the bring-up lab incurs high costs and product delays; bugs found in the field are even more expensive to repair. But for some applications, including military/aerospace, implanted medical devices, and autonomous vehicles, the consequences of a faul... » read more

The Seven Steps Of Formal Signoff


“Signoff” may be the most exciting—and frightening—word in semiconductor development. After many months, or even years of team effort, committing a design to silicon fabrication is indeed an exciting and rewarding event. But, there’s often significant anxiety involved as well – if any missed issues result in having to “turn” the chip, the increased costs and time-to-market delay... » read more

Access To Verification Knowledge While Remote Working


As someone who is used to working from home, the recent global events haven’t had as much of an impact on my ability to keep productive. Our team at OneSpin is very adept with remote-working relationships as many of us reside all over the world. Having said this, we recognize that not everyone or every company shares in this situation. Working from home can create specific challenges when ... » read more

GapFree Processor Verification


Not so long ago, many semiconductor and system suppliers developed their own processors, often with unique features geared toward specific target applications. Although this innovation has continued for specialty processors such as digital signal-processing (DSP) engines and graphics processing units (GPUs), central processing units (CPUs) largely turned into a two-contestant race between x86 a... » read more

Verification Planning And Management With Formal


Over the last twenty years, formal verification has grown from a niche technology practiced only by specialists to an essential part of mainstream chip development. Along the way, several advances were needed to make wider adoption of formal feasible. These included the standardization of assertion languages, enhanced formal engine performance and capacity, better debug capabilities, and pushbu... » read more

Functional Safety Verification For AV SoC Designs Accelerated With Advanced Tools


Autonomous vehicles (AVs) will be the culmination of dozens of highly complex systems, incorporating state-of-the-art technologies in electronics hardware, sensors, software, and more. Conceiving and designing these systems is certain to be one of the greatest challenges for today’s engineers. The only greater challenge will be convincing a wary public that these automated systems are safer d... » read more

Three Steps To Complete Reset Behavior Verification


By Chris Kwok, Priya Viswanathan, and Ping Yeung Reset architectures are notoriously complex and difficult to verify. Today’s SoCs contain highly complex reset distributions and synchronization circuitry. Often, reset trees can be larger than clock trees and have many of the same potential issues. Verifying that a design can be correctly reset under all modes of operation presents signi... » read more

Scaling Formal Connectivity Checking To Multi-Billion-Gate SoCs With Specification Automation


Connectivity checking is a popular formal verification application. Formal tools can automatically generate assertions using a specification table as input and prove them exhaustively. Simulation-based verification, on the other hand, requires significantly more effort while providing a fraction of the coverage. However, chip complexity is rapidly increasing. ASICs and FPGAs for heterogeneous c... » read more

High-Level Design And High-Level Verification


Not so long ago, some EDA vendors were painting a very attractive picture of chip design in the then-near future. The idea was that an architectural team would write a single description of the complete system in some high-level language, usually C/C++/SystemC, and that a new class of EDA tool would automatically partition the design into hardware and software, choosing the functionality of eac... » read more

Clock Domain Crossing Signoff Through Static-Formal-Simulation


By Sudeep Mondal and Sean O'Donohue Clocking issues are one of the most common reasons for costly design re-spins. This has been the driving factor in the ever-increasing demand for Clock Domain Crossing (CDC) analysis tools. Today, the majority of IP and SoC teams are focusing on “Structural CDC” analysis, which is important but not sufficient. Structural CDC analysis ensures that the d... » read more
