Post-Silicon Consistency Checking. Innovation in Verification

Post-Silicon Consistency Checking. Innovation in Verification
by Bernard Murphy on 10-26-2022 at 6:00 am

Innovation New

Many multi-thread consistency problems emerge only in post-silicon testing. Maybe we should take advantage of that fact. Paul Cunningham (Senior VP/GM, Verification at Cadence), Raúl Camposano (Silicon Catalyst, entrepreneur, former Synopsys CTO and now Silvaco CTO) and I continue our series on research ideas. As always,… Read More


Higher-order QAM and smarter workflows in VSA 2023

Higher-order QAM and smarter workflows in VSA 2023
by Don Dingee on 10-25-2022 at 10:00 am

Higher-order QAM and smarter workflows in a 5G NR example from the Keysight 89600 VSA

3GPP Release 17 and 802.11be (Wi-Fi 7) extend modulation complexity, raising the bar for conformance testing and test instrumentation to new levels. The latest release of Keysight PathWave 89600 Vector Signal Analysis 2023 (VSA 2023) software takes on higher-order QAM and smarter workflows, many customer-requested, for … Read More


The Corellium Experience Moves to EDA

The Corellium Experience Moves to EDA
by Lauro Rizzatti on 10-25-2022 at 6:00 am

Corellium SemiWIki

Bill Neifert invited me to join him on Zoom recently to talk about his move to Corellium, a company known within the DevSecOps (development, security, operations) market. Developers and security groups use its virtualization technology to build, test, and secure mobile and IoT apps, firmware, and hardware.

Not knowing much … Read More


New Cadence Joint Enterprise Data and AI Platform Dramatically Accelerates AI-Driven Chip Design Development

New Cadence Joint Enterprise Data and AI Platform Dramatically Accelerates AI-Driven Chip Design Development
by Kalar Rajendiran on 10-24-2022 at 10:00 am

1 Cadence Joint Enterprise Data and AI JedAI Platform

Without data, there is no computing field to talk about, no technology world to awe at and not much of a semiconductor industry to work in. There is no argument that data is the foundational piece for everything, has been to date and will continue to be. While processing an application’s input data is essential to serve the intended… Read More


Clock Aging Issues at Sub-10nm Nodes

Clock Aging Issues at Sub-10nm Nodes
by Daniel Payne on 10-20-2022 at 10:00 am

IC failure rate chart, clock aging

Semiconductor chips are all tested prior to shipment in order to weed out early failures, however there are some more subtle reliability effects that only appear in the longer term, like clock aging. There’s even a classic chart that shows the “bathtub curve” of failure rates over time:

If reality and expectations… Read More


The Increasing Gap between Semiconductor Companies and their Customers

The Increasing Gap between Semiconductor Companies and their Customers
by Rahul Razdan on 10-19-2022 at 6:00 am

figure1 4

Semiconductors sit at the heart of the electronics revolution, and the scaling enabled by Moore’s law has had a transformational impact on electronics as well as society.   Traditionally, the relationship between semiconductor companies and their customers has been a function of the volume driven by the customer.  In very … Read More


Balancing Analog Layout Parasitics in MOSFET Differential Pairs

Balancing Analog Layout Parasitics in MOSFET Differential Pairs

Teardrop Display
This article is an abstract of Paul Clewes’ webinar you can find here.

Differential amplifiers apply gain not to one input signal but to the difference between two input signals. This means that a differential amplifier naturally eliminates noise or interference that is present in both input signals. Differential amplification… Read More


STOP Writing RTL for Registers

STOP Writing RTL for Registers
by Steve Walters on 10-17-2022 at 6:00 am

Semifore EDA Software

After almost three decades in the EDA business, it is beyond my comprehension to understand why chip designers still hand-write RTL for complex register maps – chip designs with hundreds of registers and thousands of register fields.  In today’s silicon world where software is the key to chip-based product success, it is the register… Read More


The CHIPS and Science Act, Cybersecurity, and Semiconductor Manufacturing

The CHIPS and Science Act, Cybersecurity, and Semiconductor Manufacturing
by Simon Butler on 10-13-2022 at 10:00 am

CHIPS Act Logo

This year is proving to be a momentous one for U.S. semiconductor manufacturing. During a global chip shortage and record inflation, President Biden signed into effect the CHIPS and Science Act – which so far is the greatest boon to U.S. semiconductor manufacturing in history, with $52 billion in subsidies for chip manufacturers… Read More
