Imperas in the News

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…

RISC-V drives new attention to this market, but the cost/benefit equation is different for open-source hardware than software

Semiconductor Engineering

 

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…

Recently Embedded Magazine published a very interesting article with some insights on extending a RISC-V processor with custom instructions

Embedded

The open instruction set architecture (ISA) of RISC-V permits broad flexibility in implementation and offers optional features that can enable fresh approaches to resolving hardware-software design tradeoffs. Based on a modular structure, a number of standard extensions and options can be used to configure the base processor as a starting point.…

Designers must carefully weigh the gains against the costs, many of which are not immediately obvious

Semiconductor Engineering

While the ability to extend a processor is nothing new, market dynamics are forcing a growing percentage of the industry to consider it a necessary part of their product innovation. From small IoT functions to massive data centers and artificial intelligence, the need to create an optimized processing platform is often the only way to get more performance or lower power out of the silicon…

Design Verification (DV) test planning using a trusted SoC methodology for RISC-V processor verification including custom extension

RISC-V Processor Design Verification (DV)

Given that RISC-V is an open instruction set architecture (ISA), a RISC-V processor designer has many implementation and configuration options, plus the freedom of extending the ISA with custom instructions and extensions. While fundamentally a processor is a hardware design with the main objective of correctly executing software, it makes sense that…

When creating a new processor, how much verification is required? Setting the right ROI is important

Semiconductor Engineering

Custom processors are making a resurgence, spurred on by the early success of the RISC-V ISA and the ecosystem that is rapidly building around it. But this shift is amid questions about whether processor verification has become a lost art.
Years ago custom processors were common. But as the market consolidated around a handful of companies, so did the tools and expertise needed to develop those…

Verification tools and golden reference model provide support for RISC-V custom instruction extensions and full processor design verification

RISC-V DV

The introduction, and initial success, of the RISC-V processor ISA has reignited interest in the design of custom processors, but the industry is now grappling with how to verify them. The expertise and tools that were once in the market have been consolidated into the hands of the few companies that have been shipping processor chips or IP cores over the past 20 years.

Verification of a processor is…
