Power Estimation: Early Warning System Or False Alarm?


Semiconductor Engineering sat down with a large panel of experts to discuss the state of power estimation and to find out if the current levels of accuracy are sufficient to being able to make informed decisions. Panelists included: Leah Schuth, director of technical marketing in the physical design group at [getentity id="22186" comment="ARM"]; Vic Kularni, senior vice president and general ma... » read more

Is HW Or SW Running the Show?


In the past, hardware was designed and then passed over to the software team for them to add their contribution to the product. This worked when the amount of software content was small and the practice did not significantly contribute to product delays. Over time, the software content grew and today it is generally accepted that software accounts for more product expense than hardware, takes l... » read more

ROI Not There Yet For SysML


At some point down the road in the realm of system-level design, the Systems Modeling Language (SysML) dialect of the Unified Modeling Language (UML) standard may drive into semiconductor design. So far, however, a return on investment has not been established for its use. SysML is defined as a general-purpose visual modeling language for systems engineering applications, and it supports the... » read more

The Next Level Of Abstraction For System Design


Recently there have been a lot of discussions again about the next level of design abstraction for chip design. Are we there yet? Will we ever get there? Is it SystemC? UML/SysML perhaps? I am taking the approach of simply claiming victory: Over the last 20 years we have moved up beyond RTL in various areas—just in a fragmented way. However, the human limitations on our capacity for processin... » read more

What ESL Is Really About


There has been an almost constant disagreement between the generally held view about what ESL is and my own views on the subject. It is not completely surprising, given that I have spent most of my time as a verification specialist working within the EDA industry. EDA has been driven by design, and all of the largest EDA companies grew out of advances on the design side. [getkc id="10" kc_na... » read more

ESL: 20 Years Old, 10 To Go


It is a common perception that the rate of technology adoption accelerates. In 1873, the telephone was invented and, after 46 years, it had been adopted by one-quarter of the U.S. population. Television, invented in 1926 took 26 years. The PC in 1975 took just 16 years. It took only 7 years after the introduction of the Internet in 1991 before it was seeing significant levels of adoption. So... » read more

Mentor Buys Remainder Of Calypto


Back in 2002, a small startup company decided to tackle one of the most difficult problems in EDA—one that, if solved, could have opened up a whole new level of abstraction. Back when [getkc id="29" kc_name="logic synthesis"] was the new tool to try out, it suffered from the fact that gate-level [getkc id="11" kc_name="simulation"] had to be performed on the output, even if the input had been... » read more

Why Implementation Matters To System Design And Software


There has been quite some discussion in the recent past how well abstraction really works in enabling system design and verification. As I admitted in “Confessions of an ESL-Aholic” a while back, I have revised my view significantly over the years. While thinking originally of abstraction more as an panacea, it turns out that important decisions and analyses, such as for power and performan... » read more

What Happened To ESL


Electronic system level ([getkc id="48" kc_name="ESL"]) is a design methodology idea that gained steam in the last 20 years centered mainly around the idea of using higher levels of abstraction to define and implement an electronic design. It was defined and promoted by industry analyst Gary Smith, then at Gartner-Dataquest, and so much has been written on this topic over the years that ESL ... » read more

Poised For Aspect-Oriented Design?


In 1992, [getperson id=" 11046 " comment="Yoav Hollander"] had the idea to take a software programming discipline called aspect-oriented programming (AOP) and apply it to the verification of hardware. Those concepts were incorporated into the [gettech id="31021" t_name="e"] language and [getentity id="22068" e_name="Verisity"] was formed to commercialize it. Hollander had seen that using obj... » read more
