Toyota Unintended Acceleration

The Toyota Unintended Acceleration case has seen a lot of discussion, but much of it is, to put it mildly, not terribly well informed.  Last week at the UK’s High Integrity Software conference (look at the slides here http://his-2015.co.uk/slides )  I heard an authoritative speaker.  Prof. Philip Koopman is regularly asked to act as an expert witness on behalf of people claiming against Toyota, and acted as such in the Bookout/Schwarz trial in 2013 when a jury decided that that defects in Toyota’s Electronic Throttle Control System (ETCS) software and safety architecture caused a fatal mishap. 

As Phil is involved in on-going litigation he has to be very careful in what he says, and his talk is carefully prepared.  He has put the slides, and a video, on his website http://betterembsw.blogspot.co.uk/2014/09/a-case-study-of-toyota-unintended.html

If you have a few minutes to spare it is well worth a visit (sa is the rest of his site). If nothing else it will cause you to have severe qualms about the way in which the software was developed and the way in which people can interpret the result of investigations. I think it also raises serious questions about using normal court proceedings to get to the root of technical issues.

Overcoming Signal Integrity Challenges of 112G Connections on PCB

Sponsored by Cadence Design Systems

One big challenge with 112G SerDes is handling signal integrity (SI) issues. By the time the signal winds its way from the transmitter on one chip to packages, across traces on PCBs, through connectors or cables, and arrives at the receiver, the signal is very distorted, making it a challenge to recover the clock and data-bits of the information being transferred. Learn how to handle SI issues and ensure that data is faithfully transmitted with a very low bit error rate (BER).

Mindi Analog Simulator

Sponsored by Mouser Electronics and Microchip

It’s easy to go wrong in the analog portion of your design, particularly if you’re not an analog “expert.” Electrical simulation can help reduce risk and design re-spins. In this episode of Chalk Talk, Amelia Dalton chats with Rico Brooks of Microchip about the MPLAB Mindi tool, and how it can help reduce your design risk.
