The open standard ISA of RISC-V allows SoC developers to also build or modify a processor core optimized to the application requirements. The SoC verification tasks are adapting to address the significant increases in complexity. This article covers the 6 key components of RISC-V processor verification: The DV Plan, RTL DUT, Testbench,…

The actual time may be more of a fuzzy risk assessment than a clear demarcation.

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, verification teams continue to…

As Imperas releases advanced SystemVerilog reference technology for RISC-V processor verification it brings together Peter Flake, Simon Davidmann, and Phil Moorby to discuss their involvement in the creation of Verilog and SystemVerilog.

Oxford, UK – February 25th, 2021 – Imperas Software Ltd., the leader in RISC-V processor verification technology, today announced as part of the participation at DVCon 2021, Simon Davidmann will host a personal perspective on the…

OpenHW Processor DV Flow with Imperas RISC-V Golden Reference Model

 

The RISC-V ISA (Instruction Set Architecture) permits a range of possibilities for processor implementation with a modular approach for standard and custom extensions. In addition, implementations may be shared commercially or as open-source, and adopters beyond the original design team can use these directly or as a basis for further modifications and enhancements.
The OpenHW Group is a not-for-…

High-quality and efficient verification requires a focus on details.

Semiconductor Engineering

 

Verification is undergoing fundamental change as chips become increasingly complex, heterogeneous, and integrated into larger systems.

Tools, methodologies, and the mindset of verification engineers themselves are all shifting to adapt to these new designs, although with so many moving pieces this isn’t always so easy to comprehend. Ferreting out bugs in a design now requires a multi-faceted and more holistic approach,…

Verification IP extended with Floating-Point architectural validation test suites based on golden reference model and coverage-based development.

Imperas RISC-V Verification

Oxford, UK – January 25th, 2021 – Imperas Software Ltd., the leader in RISC-V processor verification technology, today announced the latest addition to the Imperas RISC-V Verification IP (VIP) solutions with the Floating-Point architectural validation test suites covering the RISC-V Specifications for 32bit Single-Precision (

The semiconductor industry will look and behave differently this year, and not just because of the pandemic.

Semiconductor Engineering

 

The new year will be one of significant transition and innovation for the chip industry, but there are so many new applications and market segments that broad generalizations are becoming less meaningful. Unlike in years past, where sales of computers or smart phones were a good indication of how the chip industry would fare, end markets have both multiplied and splintered, greatly increasing the number…

Using SoC methodologies for RISC-V processor DV.

The Lost Art of Processor Verification

 

As we celebrate over 50 years of microprocessors, the industry has embraced every generation of silicon process technology with architectural innovation plus new design methods that have supported innovations in almost every market segment. The interest around RISC-V is opening up increased activity around new approaches to optimize designs for the next generation of devices across multiple market segments…
