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
An Information Sharing and Analysis Center (ISAC) is essentially a trusted entity established by critical infrastructure owners and operators to share threat data. ISACs first emerged in 1998 when President Clinton issued Presidential Decision Directive 63, which identified the nation’s critical infrastructure that could… 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
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
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
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
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
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
Aerospace and defense applications have traditionally leveraged hardware-in-the-loop (HIL) testing to overcome several issues. A big one is how expensive the physical system is. Even breaking down the system into subsystems for test can still be too expensive when fielding more than a couple test stations. Modeling elements… Read More
