Gaps In Performance, Power Coverage


The semiconductor industry always has used metrics to define progress, and in areas such as functional verification significant advances have been made. But so far, no effective metrics have been developed for power, performance, or other system-level concerns, which basically means that design teams have to run blind. On the plus side, the industry has migrated from the use of code coverage... » read more

Abstraction: Necessary But Evil


Abstraction allows aspects of a design to be described in an executable form much earlier in the flow. But some abstractions are breaking down, and an increasing amount of lower-level information has to be brought upstream in order to provide estimates that are close enough to reality so informed decisions can be made. The value of abstractions in design cannot be overstated. High levels of ... » read more

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

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

Integration Or Segregation


In the Electronics Butterfly Effect story, the observation was made that the electronics industry has gone non-linear, no longer supported by incremental density and cost-reducing improvements that Moore’s Law promised with each new node. Those incremental changes, over several decades, have meant that design and architecture have followed a predictable path with very few new ideas coming in ... » read more
