I was kind of shocked when the service manager at our local VW dealership told me that one of the wires in the ignition system of my wife’s New Beetle had started to overheat, melting the insulation and becoming a safety hazard. Why didn’t a fuze just blow, protecting the wiring from overheating? We decided to quickly … Read More


3 flavors of TMR for FPGA protection

3 flavors of TMR for FPGA protection
by Don Dingee on 12-10-2015 at 4:00 pm

Back in the microprocessor stone age, government procurement agencies fell in love with the idea of radiation hardened parts that might survive catastrophic events. In those days, before rad-hard versions of PowerPC and SPARC arrived, there were few choices for processors in defense and space programs.

One of the first rad-hard… Read More

When you drive a car off the dealer’s lot, you own the whole vehicle, right? For decades, car owners have popped the hood and crawled under the car to do their own maintenance; and for those mechanically inclined, even make modifications to improve performance or handling. However, in an era where a car is increasingly controlled… Read More


To err is runtime; to manage, NoC

To err is runtime; to manage, NoC
by Don Dingee on 10-27-2015 at 12:00 pm

Software abstraction is a huge benefit of a network-on-chip (NoC), but with flexibility comes the potential for runtime errors. Improper addresses and illegal commands can generate unexpected behavior. Timeouts can occur on congested paths. Security violations can arise from oblivious or malicious access attempts.

Runtime… 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

by Daniel Payne on 08-11-2015 at 12:00 pm

Do you remember how auto maker Toyota had to pay a $1.2 billion settlement in 2014 because some of their automotive models experienced sudden, unintended acceleration? That scenario has to be an engineer’s worst nightmare because something was missed during the design and testing of an automotive electronics system that… Read More

Trends in Automotive Electronics at #52DAC
by Daniel Payne on 07-05-2015 at 4:00 pm

The coolest and most expensive car at DAC this year had to be the McLaren P1, priced at $1,150,00 and powered by a 903 hp gas/electric hybrid. Electronics are used in autos to provide safety features, infotainment, motor control and performance.

Also at DAC this year there was an Automotive Village with more cars and experts from … Read More


Turning the Automotive Development Process Upside Down

Turning the Automotive Development Process Upside Down
by Daniel Payne on 06-07-2015 at 2:00 pm

Most of us drive automobiles and have a vague idea that the development of our cars takes many years, millions of dollars, is a proprietary process and require huge factories to produce. A relatively new company called Local Motors founded in 2007 has started to turn the automotive development process upside down because they do… Read More
