Connectivity Checking Is A Perfect Fit For Formal Verification


Formal verification has traditionally been regarded as an advanced technique for experts to thoroughly verify individual blocks of logic, or perhaps small clusters of blocks. However, if you talk to anyone involved in the field these days, you’ll find that the majority of formal users are running applications (“apps”) targeted for specific verification problems. Further, many of these app... » read more

The Fibonacci Calculator


The holiday season is all about traditions, and the annual holiday puzzle has become a tradition here at OneSpin. Two years ago, we challenged engineers everywhere to solve the famous Einstein’s Riddle using a formal tool. We received some interesting solutions. Last year, we drew an even bigger response to our invitation to tackle the “World’s Hardest Sudoku.” These puzzles are fun, of... » read more

Heterogeneous Computing Raises The Bar For Functional Verification


If there’s one thing certain in chip development, it’s that every innovation in architecture or semiconductor technology puts more pressure on the functional verification process. The increase in gate count for each new technology node stresses tool capacity. Every step up in complexity makes it harder to find deep, corner-case bugs. The dramatic growth in SoC designs brings software into p... » read more

Integrating Results And Coverage From Simulation And Formal


Not so long ago, formal verification was considered an exotic technology used only by specialists for specific verification challenges such as cache coherency. As chips have grown ceaselessly in size and complexity, the traditional verification method of simulation could not keep pace. The task of generating and running enough tests consumed enormous resources in terms of engineers, simulation ... » read more

AI Chips Must Get The Floating-Point Math Right


Most AI chips and hardware accelerators that power machine learning (ML) and deep learning (DL) applications include floating-point units (FPUs). Algorithms used in neural networks today are often based on operations that use multiplication and addition of floating-point values, which subsequently need to be scaled to different sizes and for different needs. Modern FPGAs such as Intel Arria-10 ... » read more

Demystifying EDA Support For ISO 26262 Tool Qualification


My new, mid-size car is equipped with many advanced driver-assistance systems. To be honest, it’s taking me time to get used to some of them, as, for example, lane-centering assist that seamlessly takes control of my steering wheel. However, I cannot wait to get my hands off a fully autonomous vehicle and be able to take a nap while 7nm chips run machine learning and other artificial intellig... » read more

Functional Safety: Art Or Science?


Nowadays, most hardware development projects deploy functional verification flows that include UVM-based constrained-random testbenches and formal verification. High design complexity, tough budget constraints, and short time to market are the norm, not the exception. Advanced verification is a necessity for many engineering teams. In our increasingly connected world, where billions of IoT devi... » read more

The Skies Over EDA Are Finally Cloudy


EDA companies have been talking for years about providing access to their tools in the cloud, including more articles than I can count with titles about the EDA forecast being cloudy, clouds on the horizon, and so forth. The title of this post continues the dubious tradition of cloud-based puns, but there’s no future tense involved. Recent announcements from several EDA companies make it appe... » read more

Welcome Verification 3.0


Leave it to Jim Hogan, managing partner of Vista Ventures, to look further out at the changing horizon of verification than the rest of us and to make sense of it in what he calls Verification 3.0. In his executive summary, he outlined the significant advancements in functional verification over the past 20 years, such as hybrid verification platforms in Verification 1.0 and hardware/software c... » read more

A Combined Design And Verification Flow For Safety-Critical Designs


By Tom Anderson and Srikanth Rengarajan I welcome my co-author for today’s post, Srikanth Rengarajan, vice president of product and business development from Austemper Design Systems. We would like to focus on safety-critical designs, a topic very much in the news these days because of the public’s fascination with autonomous vehicles. This consumer category now joins medical electron... » read more
