Bridging the IP Divide


IP reuse enabled greater efficiency in the creation of large, complex SoCs, but even after 20 years there are few tools to bridge the divide between the IP provider and the IP user. The problem is that there is an implicit fuzzy contract describing how the IP should be used, what capabilities it provides, and the extent of the verification that has been performed. IP vendors have been trying to... » read more

FinFET Scaling Reaches Thermal Limit


In 1974, Robert H. Dennard was working as an IBM researcher. He introduced the idea that MOSFETs would continue to work as voltage-controlled switches in conjunction with shrinking features, providing doping levels, the chip's geometry, and voltages are scaled along with those size reductions. This became known as Dennard's Law even though, just like Moore's Law, it was anything but a law. T... » read more

Unintended Patent Consequences


Section 101 of the U.S. patent law limits the types of things for which patent protection can be sought. It says: "Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title." In 2012, the Supreme Court made what they t... » read more

ESL Flow is Dead


It was 20 years ago that Gary Smith coined the term [getkc id="48" comment="Electronic System Level"] (ESL). He foresaw the next logical migration in abstraction up from the [getkc id="49" comment="Register Transfer Level"] (RTL) to something that would be capable of describing and building complex electronic systems. He also saw that the future of EDA depended upon who would control that marke... » read more

System-Level Verification Tackles New Role


Wally Rhines, chairman and CEO of Mentor Graphics, gave the keynote at DVCon this year. He said that if you pull together a bunch of pre-verified IP blocks, it does not change the verification problem at the system level. That sounds like a problem. There are assumptions made that the IP blocks work to a reasonable degree, and that when performing system-level verification the focus is not a... » read more

Are Simulation’s Days Numbered?


Semiconductor Engineering sat down to discuss the limitations of simulation in more complex designs with [getperson id="11049" comment="Michael McNamara"], CEO of [getentity id="22716" comment="Adapt-IP”]; Pete Hardee, product management director at [getentity id="22032" e_name="Cadence"]; David Kelf, vice president of marketing for for [getentity id="22395" e_name="OneSpin Solutions"]; Lauro... » read more

Power Management Heats Up


Power management has been talked about a lot recently, especially when it comes to mobile devices. But power is only a part of the issue—and perhaps not even the most important part. Heat is the ultimate limiter. If you cannot comfortably place the device on your face or wrist, then you will not have a successful product. Controlling heat, at the micro and macro levels, is an important asp... » read more

Bridging The IP Divide


The adoption of an IP-based model has enabled designs to keep filling the available chip area while allowing design time to shrink. But there is a divide between IP providers and IP users. It is an implicit fuzzy contract about how the IP should be used, what capabilities it provides, and the extent of the verification that has been performed. IP vendors have been trying to formalize this as mu... » read more

A Formal Transformation


A very important change is underway in functional verification. In the past, this was an esoteric technology and one that was difficult to deploy. It was relegated to tough problems late in the verification cycle, and it was difficult to justify the ROI unless the technology actually did find some problems. But all of that has changed. Formal verification companies started to use the technology... » read more
