Experts At The Table: Black Belt Power Management
By Ann Mutschler - 14 Jun, 2012 - Comments: 0

By Ann Steffora Mutschler With approximately 80% of SoC content reused from past designs or brought in from internal and external IP sources, a significant part of a design engineer’s job today is writing glue logic and verifying to make sure the integrated system communicates as dictated by the specification. Integration challenges continue to mount with the increasing amount of black ... » read more

The Brave New World Of Modeling TSVs
By Ed Sperling - 26 May, 2012 - Comments: 0

By Ann Steffora Mutschler With 2D ICs the prevailing notion has been that wire parasitics are relatively self-contained with the exception of very advanced designs running at hundreds of gigahertz. For the most part, the package designer and IC designer lived in their own separate worlds. With the advent of chip stacking using through silicon vias (TSVs), those worlds are being thrust together... » read more

EDA’s Cloudy Vision
By Ed Sperling - 24 May, 2012 - Comments: 0

By Ann Steffora Mutschler Since the dawn of EDA, the industry has largely operated under a traditional software distribution model whereby the customer would run the software it licensed on its own hardware equipment. With the sophistication of advanced IT management techniques as well as education surrounding “The Cloud,” it may be safe to predict that engineers in the not-to-distant futu... » read more

System-Level Models Redefined
By Ed Sperling - 24 May, 2012 - Comments: 0

By Ann Steffora Mutschler It wasn’t that long ago that the promise of system-level models was an easy implementation path and the ability to then reuse the models in a different design, for a different target application. But how reusable are those models in reality? The answer depends on whom you ask. First, it is important to define what a system-level model is, noted Frank Schirrmeiste... » read more

Which Software To Use?
By Achim Nohl - 24 May, 2012 - Comments: 0

By Achim Nohl big.LITTLE processing refers to the concept of combining a high-performance ARM Cortex-A15 MPCore processor along with an energy-efficient Cortex-A7 processor. There were two primary use models recently introduced by ARM for big.LITTLE processing: task migration and MP. The big.LITTLE task migration use model is where the applications migrate between one cluster and another based... » read more

Audio Subsystems For Efficient SoC Integration
By Various Writers - 24 May, 2012 - Comments: 0

Implementing advanced audio functionality in a system-on-chip (SoC) involves integrating a range of hardware and software components, including an audio processor, audio peripherals, software drivers, and audio processing software. In this white paper, we discuss the requirements for audio solutions for processing of high-definition (HD) multi-channel audio and detail the challenges involved in... » read more

Technology Crossover Ahead
By Ed Sperling - 18 May, 2012 - Comments: 0

The attention showered upon NVM Express these days by both Synopsys (verification IP) and Cadence (subsystem) is significant. It’s the first significant opening in the enterprise computing space to emerge in years, and this is a market in which efficiency and performance are both measured and fully recognized. While SoC developers in the mobile space continue to develop power-management ca... » read more

Traversing The Abstraction Landscape
By Ed Sperling - 10 May, 2012 - Comments: 0

By Ann Steffora Mutschler Back in the early days of semiconductor design engineers could count the number of transistors on their chip with their own two eyes. They designed and worked at the same level of design abstraction when doing the timing analysis. Tools were SPICE-like, maybe abstracted with slightly simpler timing models than the SPICE-level transistor models. Thanks to Moore’... » read more

Mixed-Signal Integration Drives Platform Chips
By Ann Mutschler - 10 May, 2012 - Comments: 0

Not only are there low-power challenges with just about every design today, there are also very interesting issues concerning integration of mixed-signal onto chips. As chips are get bigger and more costly to develop, many companies are turning to platform chips that can be used in a smartphone and in a tablet with slightly different twists in the functionality of that platform chip because ... » read more

Virtual Prototyping Rocks
By Nithya Ruff - 26 Apr, 2012 - Comments: 0

By Nithya Ruff Achim Nohl was taking a well-deserved vacation last week and asked me to be his guest blogger. To many of you who are regular readers of Achim’s blog, I am new to Synopsys and joined only a few weeks ago to manage the Virtual Prototyping product. I came from Wind River where I managed Embedded Linux product marketing. Having come from 20+ years of managing software of all kind... » read more
