Simulation is no longer up to the task of system-level verification, but making the switch to hardware-assisted verification can lead to some surprises if you do not fully plan ahead.

Semiconductor Engineering

 

Emulation is emerging as the tool of choice for complex and large designs, but companies that swap from simulation to emulation increasingly recognize this is not an easy transition. It requires money, time, and effort, and even then not everyone gets it right.
Still, there are significant benefits…

riscvOVPsim™ updated for the latest RISC-V Vector Instructions Specification, for coverage-based DV methodologies with Verification IP for architectural validation

riscvOVPsim Imperas RISC-V reference model for vector extensions

Oxford, United Kingdom, October 15th, 2020 — Imperas Software Ltd., the leader in virtual platforms and high-performance software simulation, today announced that the free riscvOVPsim™ RISC-V…

NSITEXE Selects Imperas RISC-V Reference Model

 

Oxford, United Kingdom, September 24th, 2020 — Imperas Software Ltd., the leader in virtual platforms and high-performance software simulation, today confirmed the selection by NSITEXE, Inc., a group company of…

Building an open-source verification environment is not an easy or cheap task. It remains unclear who is willing to pay for it

Semiconductor Engineering

 

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…

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

 

The open specification of 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…

Sorting out what is meant by open-source verification is not easy, but it leaves the door open to new approaches

Semiconductor Engineering

 

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 …

It has been an unusual DAC this year, as the show went virtual due to the Covid-19 pandemic. There was no exhibition floor as such, but there was a comprehensive programme of keynote speeches, presentations, tutorials and panel discussions

Electronics Weekly

There was a lot of activity around RISC-V, including a presentation by Imperas Software (www.imperas.com) entitled ‘What’s Next for RISC-V? Vectors, Verification, and Value-added Extensions’. During the…

The OpenHW member-based verification team developing processor design verification test bench to validate open source cores in line with leading industry best practices

Oxford, United Kingdom, July 21st, 2020 — Imperas Software Ltd., the leader in virtual platforms and high-performance software simulation, today announced that OpenHW Group, the not-for-profit global organization set up to facilitate collaboration between hardware and software designers in the development of open-…

The July 2020 edition of Mentor Graphics', a Siemens Business, Verification Horizons article and Verification Academy presentation on RISC-V Processor DV are now available online

Verification Horizons

 

As SoC developers adopt RISC-V and the design freedoms that an Open ISA (Instruction Set Architecture) offers, DV teams will need to address the new verification challenges of RISC-V based SoCs. The established SoC verifications…
