Can Analog And Digital Get Along Better?

How to bridge analog and digital is getting renewed attention as the amount of analog content that needs to be processed balloons with consumer and industrial IoT applications. Solving that problem isn’t going to be easy, though. To begin with, digital designers view designs in terms of voltages. Analog designers, in contrast, look at currents. “Unless you can analyze an [getkc id="37... » read more

End Of Mixed Signal Engineering?

EDA companies are stepping back after years of trying to force engineers to combine analog and digital disciplines. Rather than emphasizing [getkc id="38" kc_name="mixed signal"] as a single expertise, they are building bridges and translation mechanisms between the two worlds. The moves cap more than a decade of trying to find optimal ways to pack [getkc id="37" kc_name="analog"] and digita... » read more

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

What Is ‘Digital’?

I saw a LinkedIn article with this title a couple of weeks ago and was curious. Do we not know what digital is and do we need to question it? When I read the first line I was very surprised and somewhat confused. Ved Sen, the author said that, “Despite working in the digital space for years, now I was quite stumped a few weeks ago when I was asked to define it.” Why would digital be so d... » read more

Experts At The Table: The Internet Of Everything

By Ed Sperling System-Level Design sat down to discuss the Internet of Things with Jack Guedj, president and CEO of Tensilica; John Heinlein, vice president of marketing for the physical IP division of ARM; Kamran Izadi, director of sourcing and supplier management at Cisco; and Oleg Logvinov, director of market development for STMicroelectronics’ Industrial and Power Conversion Division. Wh... » read more

Solutions For Mixed-Signal IP, IC, And SoC Implementation

Traditional mixed-signal design environments, in which analog and digital parts are implemented separately, are no longer sufficient and lead to excess iteration and prolonged design cycle time. Realizing modern mixed-signal designs requires new flows that maximize productivity and facilitate close collaboration among analog and digital designers. This paper outlines mixed-signal implem... » read more

Raising The Stakes For IP

By Ed Sperling As the amount of IP in an SoC increases, so do the number of players who want to strengthen their position in this market. The big acquisitions that began several years ago over time have proved to be just opening salvos—something that was impossible to predict when this shift began. Synopsys’ purchase of Virage Logic and Cadence’s purchase of Denali, both of which occu... » read more

Building A Better Team

One-On-One with IDT CEO Ted Tewskbury: How IDT is bridging the analog and digital engineering worlds with a mixed-signal team approach.   [youtube vid=TRfJ5a3WJrw] » read more

Exclusive Research: What’s Happening With Third-Party IP

Analog and mixed signal IP began closing the gap with digital core IP in design explorations in the first two months of this year, a clear sign that multicore systems on chip have emerged as the dominant semiconductor model and that the architecture requires both types of IP. While it’s too early to tell this year what effect that will have on overall design activity—the economy is the rea... » read more

Thinking Digital To Design Analog, And Vice Versa

By Ed Sperling Until several years ago, analog was a world apart from digital. Analog engineers could comfortably avoid many of the issues of Moore’s Law, viewing it as a costly bad habit with an equally bad outcome. Most analog engineers gloated privately that they could still develop chips at 250nm, or at worst 130nm, while their digital counterparts were struggling to keep up with is... » read more
