Whatever Happened To High-Level Synthesis?


A few years ago, [getkc id="105" comment="high-level synthesis"] (HLS) was probably the most talked about emerging technology. It was to be the heart of a new Electronic System Level (ESL) flow. Today, we hear much less about the progress being made in this area. Semiconductor Engineering sat down to discuss this with Bryan Bowyer, director of engineering for high level design and verificati... » read more

Early Power Modeling Using SystemC And TSMC System-PPA


Power consumption is often more important than performance in today’s SoC designs because of battery size and power dissipation limitations. The dilemma is that the most leverage available to optimize power consumption is at the architectural design stage, but there often is not enough information available early enough to make accurate power decisions. On the performance side, SystemC mod... » 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

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

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
