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

Week In Review: Design, Low Power
By Jesse Allen - 12 Mar, 2021 - Comments: 0

Tools & IP Codasip unveiled three commercially licensed add-ons to the Western Digital SweRV Core EH1, aiming to allow it to be designed into a wider range of applications. The SweRV Core EH1 is a 32-bit, dual-issue, RISC-V ISA core with a 9-stage pipeline, open-sourced through CHIPS Alliance. The add-ons offer a floating-point unit (FPU) that supports the RISC-V single precision [F] and d... » read more

When Is Verification Done?
By Ann Mutschler - 25 Feb, 2021 - Comments: 0

Even with the billions of dollars spent on R&D for EDA tools, and tens of billions more on verification labor, only 30% to 50% of ASIC designs are first time right, according to Wilson Research Group and Siemens EDA. Even then, these designs still have bugs. They’re just not catastrophic enough to cause a re-spin. This means more efficient verification is needed. Until then, verificati... » read more

RISC-V Becoming Less Risky With The Right Verification
By Rob van Blommestein - 25 Jan, 2021 - Comments: 1

RISC-V continues to make headlines across the electronic design industry. You may have seen the recent news that the OpenHW Group is delivering their first RISC-V core, the CV32E40P. If you attended last month’s RISC-V Summit, perhaps you attended “CORE-V: Industrial Grade Open-Source RISC-V Cores” by Rick O’Connor, president of the OpenHW Group. In this session, Rick discussed how the ... » read more

RISC-V Verification Challenges Spread
By Ann Mutschler - 22 Dec, 2020 - Comments: 0

The RISC-V ecosystem is struggling to keep pace with rapid innovation and customization, which is increasing the amount of verification work required for each design and spreading that work out across more engineers at more companies. The historical assumption is that verification represents 60% to 80% or more of SoC project effort in terms of cost and time for a mature, mainstream processor... » read more

Week In Review: Design, Low Power
By Jesse Allen - 11 Dec, 2020 - Comments: 0

RISC-V RISC-V International CEO Calista Redmond provided an update on the state of the community during the annual RISC-V Summit: “RISC-V has had an incredible year of growth and momentum. This year, our technical community has grown 66 percent to more than 2,300 individuals in our more than 50 technical and special interest groups. We’re seeing increased market momentum of RISC-V cores, S... » read more

Week In Review: Auto, Security, Pervasive Computing
By Susan Rambo - 11 Dec, 2020 - Comments: 0

Automotive Self-driving car company Cruise now has driverless cars on the streets of San Francisco, Calif., reports the San Francisco Chronicle. Cruise, which is backed by General Motors, is testing five driverless cars in the urban — and very hilly — environment of San Francisco. Cruise is using an EV — the Chevy Bolt — as a test vehicle. At Level 4 driving, the cars will not have a w... » read more

Components For Open-Source Verification
By Brian Bailey - 02 Sep, 2020 - Comments: 2

Defining an open-source verification methodology is a lot more difficult than just developing an open-source simulator. This is the reality facing open-source hardware such as RISC-V. Some people may be asking for the corresponding open-source verification, but that is a much tougher problem — and it is not going to be solved in the short term. Part one examined the reasons why open-source... » read more

Open-Source Verification
By Brian Bailey - 30 Jul, 2020 - Comments: 1

Ask different people what open-source verification means and you will get a host of different answers. They range from the verification of open-source hardware, to providing an open-source verification infrastructure, to providing open-source stream generators or reference models, to open-source simulators and formal verification engines. Verification is about reducing risk. "Verification is... » read more

Open-Source Hardware Momentum Builds
By Brian Bailey - 25 Jun, 2020 - Comments: 2

Open-source hardware continues to gain ground, spearheaded by RISC-V — despite the fact that this processor technology is neither free nor simple to use. Nevertheless, the open-source hardware movement has established a solid foothold after multiple prior forays that yielded only limited success, even for processors. With demand for more customized hardware, and a growing field of startups... » read more
