Imperas announce the latest RISC-V test suites are now available free with riscvOVPsimPlus

RISC-V Architectural Validation test suites updated for the ratified extensions including Vectors, Crypto (scalar), Bit Manipulation, and the new addition of Embedded (E) extension

Oxford, United Kingdom, July 6th, 2022 -- Imperas Software Ltd., the leader in RISC-V simulation solutions, today announced the latest RISC-V test suites and updates to the free riscvOVPsimPlus reference model, simulator and test suites. Independently developed Verification IP (VIP) plays an important role in any verification plan since RISC-V developers’ interpretation of the specification are best tested against an independent reference. Architectural Validation test suites are important for RISC-V to ensure hardware implementations are in line with expectations of the software ecosystem supporting RISC-V.

In May 2022 RISC-V International's Architectural Test SIG (formerly the compliance working group) moved to using a Python program/framework v3.0 to run compliance testing and no longer provides signatures or scripts to run targets against their tests. As a service to RISC-V processor developers, Imperas has ported the RVI tests to the Imperas test framework and makes them available as part of the Imperas test downloads. This means you can use all of the Imperas tests and all of the RVI tests from one simple make/bash framework. The RISC-V International tests have the -RVI suffix with further information available at https://www.ovpworld.org/riscvOVPsimPlus.

riscvOVPsimPlus includes Architectural Validation test suites totaling over 8.6 million instructions, available as open-source and include:

Configured: spec:1.0.0, xlen:32, elen:32, vlen:256, slen:256, FP:IEEE754
Note ImperasDV users can access other configs of spec, xlen, elen, vlen, slen

RISC-V Specifications supported in riscvOVPsimPlus

In addition, the following specification extensions are available to ImperasDV commercial users

“With all the desi

gn freedoms that RISC-V offers, verification has never been more important to ensure full ecosystem support for new processor implementations,” said Simon Davidmann, CEO at Imperas Software Ltd. “The best test for a processor is simulation-based testing to verify the interaction between the software program and the hardware operation. Architectural Validation test suites, while not a complete verification plan, offer the basic confirmation necessary to sustain the ecosystem of software support. We are pleased to offer the latest suites for the key ratified specifications of Vectors, Bit Manipulation and Crypto plus the new Embedded E suite, all for free including commercial use, with riscvOVPsimPlus.”

Availability



RISC-V IP Cores

The free riscvOVPsimPlus package, including the Imperas RISC-V Reference Model, latest test suites and instruction coverage analysis, including updates for the latest RISC-V ratified specifications is now available on OVPworld at www.ovpworld.org/riscvOVPsimPlus.

Validation tests for the Vector extension and the privilege PMP (Physical Memory Protection) unit are available to Imperas users and are configured to users’ specific hardware option settings.

The ImperasDV RISC-V processor verification technology is already in active use with many leading customers, some of which have working silicon prototypes and are now working on 2nd generation designs. These customers, partners and users span the breadth of RISC-V adopters from open source to commercial; research to industrial; microcontrollers to high performance computing. A select sample of these include - Codasip, EM Microelectronics (Swatch), NSITEXE (Denso), Nvidia Networking (Mellanox), OpenHW Group, MIPS Technology, Seagate Technology, Silicon Labs, and Valtrix Systems, plus many others yet to be made public.

ImperasDV is available now, more details are available at Imperas.com/ImperasDV.
