Circuit Reliability Verification For Automotive Electronics
By Matthew Hogan - 06 May, 2021 - Comments: 0

By Matthew Hogan and Dina Medhat In the automotive industry, reliability and high quality are key attributes for electronic automotive systems and controls. Naturally, they are particularly crucial when developing functional safety (FuSa) solutions, where inadequate performance or product failure can lead to injury or death. When it comes to safety-related automotive electronics, ISO 26262 p... » read more

Steep Spike For Chip Complexity And Unknowns
By Ed Sperling - 05 May, 2021 - Comments: 0

Cramming more and different kinds of processors and memories onto a die or into a package is causing the number of unknowns and the complexity of those designs to skyrocket. There are good reasons for combining all of these different devices into an SoC or advanced package. They increase functionality and can offer big improvements in performance and power that are no longer available just b... » read more

New Methodologies Create New Opportunities
By Brian Bailey - 27 Apr, 2021 - Comments: 0

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

The Verification Mindset
By Ann Mutschler - 26 Apr, 2021 - Comments: 2

The practice of semiconductor verification has changed substantially over the years, and will continue to do so. The skillset needed for functional verification 20 years ago is hardly recognizable as a verification skillset today, and the same should be expected moving forward as design and verification becomes more abstract, the boundary of what is implemented in hardware versus firmware and s... » read more

Adding Value To Open-Source RISC-V Cores With Verification
By Lee Moore - 22 Apr, 2021 - Comments: 0

By Steve Richmond (Silicon Labs), Mike Thompson (OpenHW Group), and Lee Moore (Imperas Software) Modern SoC verification has matured to the point that some are suggesting the use of the word ‘prototype’ when referring to the first silicon samples is now unnecessary. This is due in part to the commercial EDA industry, which has provided the innovation and tools used throughout the design... » read more

Merging Verification And Test
By Brian Bailey - 22 Apr, 2021 - Comments: 0

While the disciplines of functional verification and test serve different purposes, their histories were once closely intertwined. Recent safety and security monitoring requirements coupled with capabilities being embedded into devices is bringing them closer together again, but can they successfully cooperate to bring about improvements in both? Getting there may be difficult. Three phases ... » read more

RISC-V Targets Data Centers
By Ann Mutschler - 22 Apr, 2021 - Comments: 0

RISC-V vendors are beginning to aim much higher in the compute hierarchy, targeting data centers and supercomputers rather than just simple embedded applications on the edge. In the past, this would have been nearly impossible for a new instruction set architecture. But a growing focus on heterogeneous chip integration, combined with the reduced benefits of scaling and increasing demand for ... » read more

Requirements For Exhaustive SoC Reset Domain Crossing Checks
By Joe Mallett - 13 Apr, 2021 - Comments: 0

It is common to read that the numbers of clock domains and power domains in system-on-chip (SoC) designs are increasing, but for some reason there is less discussion about resets. There is no doubt that the number of reset domains is also rising; studies have shown that the single reset of twenty years ago has been replaced by a complex network of 40-50 domains in many chips and even 150 in som... » read more

Verification Effectiveness In The Face Of FPGA Complexity: The 2020 Wilson Research Group Functional Verification Study
By Harry Foster - 08 Apr, 2021 - Comments: 0

Making informed decisions backed by good data is the key to success in highly competitive, robust markets such as FPGA design and verification. Helping our community in that endeavor is the motivation behind the worldwide Wilson Research Group Functional Verification Study. We also use that information to make sure our research and development efforts continue to deliver the solutions our cu... » read more

Interconnects In A Domain-Specific World
By Brian Bailey - 08 Apr, 2021 - Comments: 0

Moving data around is probably the least interesting aspect of system design, but it is one of three legs that defines the key performance indicators (KPI) for a system. Computation, memory, and interconnect all need to be balanced. Otherwise, resources are wasted and performance is lost. The problem is that the interconnect is rarely seen as a contributor to system functionality. It is seen... » read more
