Update on SystemC for High-Level Synthesis

Update on SystemC for High-Level Synthesis
by Tom Dillinger on 03-26-2019 at 12:00 am

The scope of current system designs continues to present challenges to verification and implementation engineering teams. The algorithmic complexity of image/voice processing applications needs a high-level language description for efficient representation. The development and testing of embedded firmware routines… Read More

Image RemovedThe ECU. That was the service department prognosis on the root cause of thealways-on air bag safety light on my immaculate car. Ten years ago the cost for its replacement with after market part was at par with getting a new iPhone 8. Today, we could get four units for the same price and according to data from several research… Read More


Virtual Prototyping With Connection to Assembly

Virtual Prototyping With Connection to Assembly
by Bernard Murphy on 08-31-2017 at 7:00 am

Virtual prototyping has become popular both as a way to accelerate software development and to establish a contract between system/software development teams and hardware development and verification. System companies with their tight vertical integration lean naturally to executable contracts to streamline communication… Read More


Getting out of DIY mode for virtual prototypes

Getting out of DIY mode for virtual prototypes
by Don Dingee on 09-26-2016 at 4:00 pm

Virtual prototyping has, inexplicably, been largely a DIY thing so far. Tools and models have come from different sources with different approaches, and it has been up to the software development team to do the integration step and cobble together a toolchain and methodology that fits with their development effort.

That integration… Read More


Climbing the Infinite Verification Mountain

Climbing the Infinite Verification Mountain
by Bernard Murphy on 06-14-2016 at 7:00 am

Many years ago I read a great little book by Rudy Rucker called “Infinity and the Mind”. This book attempts to Image Removedexplain the many classes of mathematical infinity (cardinals) to non-specialists. As he gets to the more abstract levels of infinity, the author has to resort to an analogy to give a feel for extendible and other… Read More

It has been almost five years since Marc Andreessen wrote the words, “Software is eating the world.” The premise of his essay in the Wall Street Journal in 2011 was pretty simple: the technology world has seen its intrinsic value shift from hardware to software. New all-software names have appeared on the list of high flying companies,… Read More

Automotive MCU code fault-busting with vHIL
by Don Dingee on 09-30-2015 at 7:00 pm

With electronic and software content in vehicles skyrocketing, and the expectations for flawless operation getting larger, the need for system-level verification continues to grow. Last month, we looked at a Synopsys methodology for virtual hardware in the loop, or vHIL… Read More

We’re putting the finishing touches on Chapter 9 of our upcoming book on ARM processors in mobile, this chapter looking at the evolution of Qualcomm. One of the things that made Qualcomm go was their innovative use of digital simulation. First, simulation proved out the Viterbi decoder (which Viterbi wasn’t convinced had a lot … Read More


Non-separation of power and performance

Non-separation of power and performance
by Don Dingee on 06-04-2014 at 2:00 pm

How much power does a system consume? The simplistic path to power estimation for a system used to be tossing a few metrics – standby, typical, worst case, with figures pulled from a datasheet, simulation, or physical measurement – into a spreadsheet. After filling the remaining holes with SWAG (scientific wild-ass guesses), … Read More


Book review: “shift left” with virtual prototypes

Book review: “shift left” with virtual prototypes
by Don Dingee on 03-26-2014 at 1:00 pm

Shipping a product with complete software support at official release is a lot more difficult than it sounds. Inevitably, there is less than enough hardware to go around, and what little there is has to fill the needs of hardware designers, test and certification engineers, software development teams, systems integration teams,… Read More
