IP Becoming More Complex, More Costly


Success in the semiconductor intellectual property (IP) market requires more than a good bit of RTL. New advances mandate a complete design, implementation, and verification team, which limits the number of companies competing in this market. What constitutes an IP block has changed significantly since the concept was first introduced in the 1990s. What was initially just a piece of RTL (reg... » read more

Choosing Which Tasks To Optimize In Chips


The optimization of one or more tasks is an important aspect of every SoC created, but with so many options now on the table it is often unclear which is best. Just a few years ago, most people were happy to buy processors from the likes of Intel, AMD and Nvidia, and IP cores from Arm. Some even wanted the extensibility that came from IP cores like Tensilica and ARC. Then, in 2018, John Henn... » read more

Week In Review: Design, Low Power


Tools & IP Imperas Software introduced the RISC-V Verification Interface (RVVI). The open standard and methodology can be adapted to any configuration permitted within the RISC-V specifications. RVVI defines interfaces between RTL, reference model, and testbench for RISC-V design verification, with the aim of making RISC-V processor DV reusable. It supports multi-hart, superscalar, and out... » read more

Why RISC-V Is Succeeding


There is no disputing the excitement surround the introduction of the RISC-V processor architecture. Yet while many have called it a harbinger of a much broader open-source hardware movement, the reasons behind its success are not obvious, and the implications for an expansion of more open-source cores is far from certain. “The adoption of RISC-V as the preferred architecture for many sili... » read more

Week In Review: Design, Low Power


Nvidia's proposed acquisition of Arm is officially off. The deal faced significant pushback from regulatory agencies in the UK, USA, and Europe, which feared it would reduce or limit competition in areas like data center. Nvidia indicated it would continue working with Arm, and it will retain a 20-year Arm license. (SoftBank will retain the $1.25 billion prepaid by Nvidia.) SoftBank said it wil... » read more

High-Level Synthesis For RISC-V


High-quality RISC-V implementations are becoming more numerous, but it is the extensibility of the architecture that is driving a lot of design activity. The challenge is designing and implementing custom processors without having to re-implement them every time at the register transfer level (RTL). There are two types of high-level synthesis (HLS) that need to be considered. The first is ge... » read more

RISC-V’s Expanding Footprint


Zdenek Prikryl, CTO of Codasip, sat down with Semiconductor Engineering to talk about the RISC-V market, where this open instruction set architecture (ISA) is gaining ground, and what are the biggest challenges in working with this technology. SE: Where do you see the value in RISC-V? Is it for off-the-shelf processors or more customized components? Prikryl: A few years ago, RISC-V was us... » read more

Week In Review: Design, Low Power


Cadence signed a deal to buy National Instruments’ AWR business unit for about $160 million in cash, a move that Cadence describes as a way to broaden its market into intelligent system design. AWR’s strength is high-frequency RF design automation tools, particularly in the millimeter wave and microwave spectrums, which are critical for radar and 5G. It also has technology for III-V materia... » read more

Open Source Processors: Fact Or Fiction?


Open source processors are rapidly gaining mindshare, fueled in part by early successes of RISC-V, but that interest frequently is accompanied by misinformation based on wishful thinking and a lack of understanding about what exactly open source entails. Nearly every recent conference has some mention of RISC-V in particular, and open source processors in general, whether that includes keyno... » read more

Week In Review: Design, Low Power


Tools & IP OneSpin revealed its latest formal app, Connectivity XL, providing formal connectivity checking to 7nm, multi-billion gate SoC designs. The app generates detailed connectivity specification tables from abstract connectivity specs through a dedicated checking engine that integrates structural and formal analysis to perform on-the-fly, automated abstractions. It supports verificat... » read more
