Scaling Anti-Tamper Protection To Meet Escalating Threats


Anti-tamper tends to be one of those catchall phrases encompassing any countermeasure on a security chip. A more precise definition would be that anti-tamper protection is any collection of countermeasures that serves to thwart an adversary’s attempt to monitor or affect the correct operation of a chip or a security core within a chip. Given that, it can be useful to think about a hierarchy o... » read more

How To Meet Functional Safety Requirements With Built-In-Self-Test


With the rapid growth in semiconductor content in today’s vehicles, IC designers need to improve their process of meeting functional safety requirements defined by the ISO 26262 standard. The ISO 26262 standard defines the levels of functional safety, known as Automotive Safety Integrity Level (ASIL), and is a mandatory part of an automotive system design process. The ASIL categories range... » read more

Don’t Underestimate The Multiphase Buck Voltage Regulator


Step-down (buck) voltage regulators have long been the preferred DC-DC conversion electronic workhorse thanks to their inherently high efficiency. Only in buck mode the current is directed to the output during the entire cycle. The higher delivery of current to the output, per cycle, makes the buck converter the most efficient architecture. As one of many examples, modern microprocessors, from ... » read more

3 Ways To Improve Design Collaboration: Part 2


In the last blog in this series, we talked about how VDD can help design and layout engineers work more efficiently. Communicating precise and accurate information is a key factor in improving productivity, estimates, and the planning process. Visualizing the changes makes it easier to follow the technical details. The ECO (Engineering Change Order) phase is an important phase in the lifecycle... » read more

Building Your Own NoC And The Hazards Of (Not) Changing


There is a perennial challenge that all R&D organizations face – how much of what we develop is essential to our competitive advantage and how much can be acquired at lower cost and risk rather than built from scratch? It’s easy to believe in the heat of battle that everything we are doing must be crucial. But the world continues to change around us. What was optional yesterday may be e... » read more

Faster Formal Verification Closure For Datapaths In AI Designs


In recent years, many longstanding assumptions about formal verification have been rendered obsolete by ever-improving technology. Applications such as connectivity checking have shown that formal can work on large system-on-chip (SoC) designs, not just small blocks. Standard SystemVerilog Assertions (SVA) have eliminated the need to learn an abstruse mathematical language for each new formal t... » read more

Data Strategy Shifting Again In Cars


Carmakers are modifying their data processing strategies to include more processing at or near the source of data, reducing the amount of data that needs to be moved around within a vehicle to both improve response time and free up compute resources. These moves are a world away from the initial idea that terabytes of streaming data would be processed in the cloud and sent back to the vehicl... » read more

AI Drives A New Wave For Semiconductors


In Cadence's recent earnings call, Lip-Bu Tan, our CEO, talked about the five waves that are hitting us simultaneously. Here's what he said: First of all, I'm excited about this industry, because it's very unusual to have five major waves happening at the same time. You have the AI machine learning wave and you have 5G is starting to deploy and then you have the hyperscale guy, the really mas... » read more

What Makes A Chip Tamper-Proof?


The cyber world is the next major battlefield, and attackers are busily looking for ways to disrupt critical infrastructure. There is widespread proof this is happening. “Twenty-six percent of the U.S. power grid was found to be hosting Trojans," said Haydn Povey, IAR Systems' general manager of embedded security solutions. "In a cyber-warfare situation, that's the first thing that would b... » read more

eFPGA As Fast And Dense As FPGA, On Any Process Node


A challenge for eFPGA when we started Flex Logix is that there are many customers and applications, and they all seemed to want eFPGA on different foundries, different nodes and different array sizes. And everyone wanted the eFPGA to be as fast and as dense as FPGA leaders’ on the same node. Oh, and customers seem to wait to the last minute then need the eFPGA ASAP. Xilinx and Altera (Intel ... » read more
