Verification Signoff Beyond Coverage

A common design view of verification signoff is to start with a comprehensive verification plan, covering every requirement defined among specifications and use-cases, the architectural definition, and any other relevant documents. Tests are then developed to cover every feature of the verification plan. Those tests are run and debugged, and identified issues are addressed within the design. Th... » read more

Ethical Coverage

How many times have you heard statements such as, "The verification task quadruples when the design size doubles?" The implication is that every register bit that is created has doubled the state space of the design. It gives the impression that complete verification is hopeless, and because of that little progress has been made in coming up with real coverage metrics. When constrained rando... » read more

Dependable Verification Is The Foundation ICs Require

As our world becomes increasingly high-tech, it is easy to lose sight of the little things that make all of our fancy gadgets achieve optimal performance. The one thread that enables you to get all of the benefits of a new laptop, tablet, smartphone, or your automobile’s digital dashboard and connects the components that ensure best performance is the integrated circuit (IC). For as breath... » read more

Veloce Coverage App And Veloce Assertion App Deliver Unified Coverage Methodology

The interoperability of the Veloce Coverage app and the Veloce Assertion app with other verification engines (simulation and formal) enables merging coverage collected by each engine and provides a cohesive coverage closure report and analysis flow. It enables the verification team and product-level management to make important decisions such as coverage closure sign-off, test quality analysis ... » read more

Bug Hunt! Spiraling In On Formal Coverage Closure

By Mark Eslinger and Jin Hou Many companies have used formal verification to verify complex SoCs and safety-critical designs. Using formal verification to confirm design functionalities and to uncover functional bugs is emerging as an efficient verification approach. Although formal verification will not handle the complexity of a design at the SoC level, it is an efficient tool to verify th... » read more

Challenges With Stacking Memory On Logic

Experts at the Table: Semiconductor Engineering sat down to discuss the changes in design tools and methodologies needed for 3D-ICs, with Sooyong Kim, director and product specialist for 3D-IC at Ansys; Kenneth Larsen, product marketing director at Synopsys; Tony Mastroianni, advanced packaging solutions director at Siemens EDA; and Vinay Patwardhan, product management group director at Cadence... » read more

Intelligent Coverage Optimization: Verification Closure In Hyperdrive

Coverage dominates every aspect of verification for today’s complex IP and chip designs. Coverage metrics provide critical feedback on what has been verified and what has not, especially when automated stimulus generation techniques are used. All modern hardware design and verification languages include constructs for functional coverage specification and support a range of structural coverag... » read more

Precision: A Case Study For Success

Recently, I was watching a documentary on the NASA Perseverance mission to Mars. I’ve always been fascinated by space travel and the engineering efforts to make it happen. We’ve all heard that the landing for this trip to Mars was the most precise in history, but what the documentary brought to light is the precision involved in each and every aspect of the Perseverance Rover design and dev... » 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

Better Quality RTL

How do you measure the quality of RTL? Philippe Luc, director of verification at Codasip, talks about identifying bugs, improving the overall quality of the verification, what happens when different blocks are used in a design, and how to improve efficiency in the verification process. » read more
