Week In Review: Design, Low Power


Tools & IP Codasip unveiled three commercially licensed add-ons to the Western Digital SweRV Core EH1, aiming to allow it to be designed into a wider range of applications. The SweRV Core EH1 is a 32-bit, dual-issue, RISC-V ISA core with a 9-stage pipeline, open-sourced through CHIPS Alliance. The add-ons offer a floating-point unit (FPU) that supports the RISC-V single precision [F] and d... » read more

An Integrated Approach To Power Domain And CDC Verification


Reducing power consumption is essential for both mobile and data center applications. Yet it is a challenge to lower power while minimally impacting performance. The solution has been to partition designs into multiple power domains which allow selectively reducing voltage levels or powering off partitions. Traditional low power verification validates only the functional correctness of power... » read more

Tradeoffs To Improve Performance, Lower Power


Generic chips are no longer acceptable in competitive markets, and the trend is growing as designs become increasingly heterogeneous and targeted to specific workloads and applications. From the edge to the cloud, including everything from vehicles, smartphones, to commercial and industrial machinery, the trend increasingly is on maximizing performance using the least amount of energy. This ... » read more

Nine Effective Features Of NVMe Verification IP For PCIe-Based SSD Storage


Non-Volatile Memory Express (NVMe) is a new software interface optimized for PCIe Solid State Drives (SSD). This paper provides an overview of the NVMe specification and examines some of its key features. We will discuss its pros and cons, compare it to other conventional technologies, and point out key areas to focus on during its verification. You will learn how NVMe Questa Verification IP... » read more

Blog Review: March 10


Siemens EDA's Harry Foster checks out how the maturity of verification processes impact bug escapes in FPGA designs and whether safety critical development processes prevent bugs from escaping to silicon. Synopsys' Dennis Kengo Oka examines the weaknesses and vulnerabilities in automotive keyless entry systems and how security researchers hacked the Tesla Model X key fob. Cadence's Paul M... » read more

Preventing Chips From Burning Up During Test


It’s become increasingly difficult to manage the heat generated during IC test. Absent the proper mitigations, it’s easy to generate so much heat that probe cards and chips literally can burn up. As a result, implementing temperature-management techniques is becoming a critical part of IC testing. “We talk about systems, saying the system is good,” said Arun Krishnamoorthy, senior... » read more

Design Issues For Chips Over Longer Lifetimes


Semiconductor Engineering sat down to discuss the myriad challenges associated with chips used in complex systems over longer periods of time them with Jean-Marie Brunet, senior director for the Emulation Division at Siemens EDA; Frank Schirrmeister, senior group director for solution marketing at Cadence; Maurizio Griva, R&D Manager at Reply; and Laurent Maillet-Contoz, system and architec... » read more

Over-the-Air Automotive Updates


Modern vehicles are increasingly-connected devices with growing volumes of electronic systems. This systemic complexity means that even an average vehicle design will include over 150 ECUs, which control not just infotainment and communications, but powertrain, safety, and driving systems (figure 1). We see not just a surge in the volume and complexity of electronic hardware, but also software.... » read more

Blog Review: March 3


Siemens EDA's Ray Salemi considers incrementalism in engineering, the transition from drawing circuits to writing RTL, and the next big leap of using proxy-driven testbenches written in Python. Cadence's Shyam Sharma looks at key changes from LPDDR5 in the LPDDR5X SDRAM standard, which extends clock frequencies to include 937MHz and 1066MHz resulting in max data rates of 7500MT/s and 8533 MT... » read more

Chiplets For The Masses


Chiplets are a compelling technology, but so far they are available only to a select few players in the industry. That's changing, and the industry has taken little steps to get there, but timing for when you will be able to buy a chiplet to integrate into your system remains uncertain. While new fabrication nodes continue to be developed, scaling is coming to an end, be it for physical or e... » read more
