FPGA Technology and Software IP in Power Electronics Applications

FPGAs and Plug-in Hybrid Vehicles

During the summer, I have had the chance to drive during one week one of the five Toyota Plug-in Hybrid currently under test in Canada. Those vehicles are part of a experimental project involving Toyota and canadian universities, among them Université Laval and its power electronics lab LEEPCI (my former lab). Click here to see the public announcement made with Toyota during the summer.

The vehicle is actually working very fine and it is a real pleasure to drive. For those interested, I did use only 3L of gas for normal use during the week (around 80km) which is very energy efficient! Click on the figure below to see more pictures of the car :

Where’s the link with this blog ? EV are obviously heavy power electronics applications by being used to convert energy stored in the batteries to the motor and vice-versa (motor to batteries while braking). Where’s the link with FPGAs? You may be interested to read this SAE Report written by Delphi people in 2006 and titled “FPGA considerations for Automotive applications”. According to its authors,

The complexity of automotive products will continue to increase, even as the pressure to decrease the development cycle, decrease cost, and increase quality and reliability mounts. FPGA usage to meet application needs will continue to grow as a means of reducing cycle time and development costs. Understanding and developing all aspects of FPGA manufacturing, design, implementation, application usage and performance can address the quality and reliability aspects of using FPGAs as product solutions. A low unit cost should not be the only major driving factor in choosing an FPGA. It has been shown that there are other items that can significantly add to unit cost based on the design methodology used for the implementation and verification of an FPGA. The complexity and challenge of implementing an FPGA device will erode any advantages of a traditional design flow. FPGA development requires discipline in assuring adherence to robust practices.

Briefly, they mean to have a look to the total cost of ownership (TCO) against other IC solutions.
