Mixed-Signal Design Powers Ahead


Mixed-signal devices are at the heart of many advanced systems today because of the need to interact with the outside world, but designing and verifying these systems is getting harder. There are several reasons for this. First, almost all of these devices now have to be lower power than in the past, and in the analog space it's not as simple as just dialing down part of a block. Second, it ... » read more

Verification Facing Unique Inflection Point


The Design and Verification Conference and Exhibition (DVCon) attracted more than 1,100 people to San Jose last week, just slightly less than last year. While a lot of focus, and most of the glory, goes to design within semiconductor companies, it is verification where most of the advancements are happening and thus the bigger focus for DVCon. The rate of change in verification and the producti... » read more

How Many Cores? (Part 1)


The optimal number of processor cores in chip designs is becoming less obvious, in part due to new design and architectural options that make it harder to draw clear comparisons, and in part because just throwing more cores at a problem does not guarantee better performance. This is hardly a new problem, but it does have a sizable list of new permutations and variables—right-sized heteroge... » read more

Powerful New Standard


In December 2015, the IEEE released the latest version of the 1801 specification, titled the IEEE standard for design and verification of low-power integrated circuits, but most people know it as UPF or the Unified Power Format. The standard provides a way to specify the power intent associated with a design. With it, a designer can define the various power states of the design and the contexts... » read more

Reaching For ROI


The simplest way to assess power and performance ROI of a chip design is to ask if the chip works and whether it meets the design specifications. But chips can be used in very different ways, and a single chip may have a number of operational modes, so that formula isn't so clear anymore. "Preventing failures is the No. 1 priority when it comes to ROI," said Aveek Sarkar, vice president of p... » read more

Why Power Modeling Is So Difficult


Power modeling has been talked about for years and promoted by EDA vendors and chipmakers as an increasingly important tool for advanced designs. But unlike hardware and software modeling, which have been proven to speed time to market for multiple generations of silicon, power modeling has some unique problems that are more difficult to solve. Despite continued development in this field, po... » read more

Debug Becomes A Bigger Problem


The EDA industry has invested enormous amounts of time and energy on the verification process, including new languages, new tools, new class libraries, new methodologies. But the one part of the cycle that defines that type of automation is debug. Development teams are spending half of their time in the debug process and the problem is growing. Part of the reason is that design and debug are... » read more

Adventures In Assembly


With so few [getkc id="81" kc_name="SoC"] designs — if any — today designed completely new from the ground up, the assembly task is an extremely important one to get right. [getkc id="43" kc_name="IP"] components must be put together optimally and efficiently to perfectly match the application requirements, which is complex and intricately nuanced. How companies approach IP varies signif... » read more

Thermal Damage To Chips Widens


Heat is becoming a much bigger problem for semiconductor and system design, fueled by higher density and the increasing use of complex chips in markets such as automotive, where reliability is measured in decade-long increments. In the past, heat typically was handled by mechanical engineers, who figured out where to put heat sinks, fans, or holes to funnel heat out of a chassis. But as more... » read more

Powerful New Standard


In December the IEEE released the latest version of the 1801 specification, entitled the IEEE standard for design and verification of low-power integrated circuits. Most people know it as UPF, or the Unified Power Format. That was the name the first version of it held while being developed within Accellera. The standard provides a way to specify the power intent associated with a design, enabli... » read more
