The Growing Uncertainty Of Sign-Off At 7/5nm


Having enough confidence in designs to sign off prior to manufacturing is becoming far more difficult at 7/5nm. It is taking longer due to increasing transistor density, thinner gate oxides, and many more power-related operations that can disrupt signal integrity and impact reliability.  For many years, designers have performed design rule checks as part of physical verification of the desi... » read more

The Limits Of Energy Harvesting


Energy harvesting, once considered an inexpensive alternative to low-power design and a way of achieving nearly unlimited power in mobile devices, has settled down to more modest expectations. This approach to generating energy through a variety of means—from solar to motion to ambient RF and even pH differences between soil and trees—has been proven to work. The problem is that it doesn... » read more

Raising The Abstraction Level For Power


Power-aware design is still a relatively new concern for many semiconductor products, and since inception it has changed several times and in different ways. Initially people were concerned about peak power. Today, they care about peak, total energy, thermal and other effects. The industry has tried several abstractions ranging from system-level analysis, which promised to swamp implementati... » read more

Blog Review: May 8


Synopsys' Taylor Armerding warns that the threat of cyber war on the financial system is a real possibility and points to four major vulnerability concerns. Cadence's Meera Collier takes a look at bees and technology, from smart hives to sensors that can be carried on the insects' backs. Mentor's Brent Klingforth argues that electrical and mechanic designers need to seamlessly share infor... » read more

5G Heats Up Base Stations


Before 5G can be deployed commercially on a large scale, engineers have to solve some stubborn problems—including how to make a hot technology a whole lot cooler. 5G-capable modem chipsets are already on the market from Qualcomm, Samsung, Huawei, MediaTek, Intel and Apple, with some 5G service (LTE-Advanced/LTE-Advanced Pro) available in the U.S. But still mostly missing from the 5G equati... » read more

IP Requires System Context At 6/5/3nm


Driven by each successive generation of semiconductor manufacturing technology, complexity has reached dizzying levels. Every part of the design, verification and manufacturing is more complicated and intense the more transistors are able to be packed onto a die. For these reasons, the entire system must be taken into consideration as a whole – not just as individual building blocks as could ... » read more

Blog Review: May 1


Synopsys' Melissa Kirschner questions whether a unified standard for safety-related code development will be enough to secure connected cars as MISRA and AUTOSAR merge C++ guidelines. In a podcast, Mentor's Brent Klingforth and John McMillan share questions and answers about rigid-flex PCB design, including the value of incorporating flexible circuits and the key challenges faced when doing ... » read more

Week In Review: Design, Low Power


A new working group has been proposed by Accellera to focus on the standardization of analog/mixed signal extensions (AMS) for the Universal Verification Methodology (UVM) standard. “Our ambition is to apply UVM for both digital and analog/mixed-signal verification,” said Martin Barnasconi, Accellera Technical Committee Chair. “The UVM-AMS PWG will assess the benefits of creating analog a... » read more

Automotive, AI Drive Big Changes In Test


Design for test is becoming enormously more challenging at advanced nodes and in increasingly heterogeneous designs, where there may be dozens of different processing elements and memories. Historically, test was considered a necessary but rather mundane task. Much has changed over the past year or so. As systemic complexity rises, and as the role of ICs in safety-critical markets continues ... » read more

CDNLive 2019: The Verification Ecosystem Is Growing Stronger And Stronger


Ecosystems are not only fascinating when it comes to processors like Arm, MIPS, x86, and RISC-V (as I have written before) or for semiconductor technologies like TSMC, GLOBALFOUNDRIES, and Samsung; they are key for success in verification as well. CDNLive Silicon Valley was, again, a great example of the verification ecosystem in action. It showcased the different engines verification tools run... » read more
