Automotive Semiconductors
“It is now estimated that the cost of the electronics in a
new car rises by 9-16 percent each year. In the 2001
model year, electronics accounted for 19 percent of a
mid-sized vehicle's cost. In the year 2005, it may be 25
percent for mid-sized cars and possibly 50 percent for
luxury models. ”

Driver Support Systems:
Car Driver Assistance
• Driver and passenger safety is a primary concern of the automotive
industry
• Car driver assistance augments physical safety systems such as
air bags, side impact protection…
• Latest car drive assistance systems based on:
– Video processing systems - rear view mirror & dash board
– Monitors condition out side (collision avoidance) and inside (if the driver falls
asleep!)
• If the driver drives erratically or a collision is about to happen the
system will bring the car to a halt or try to avoid the collision
• Xilinx FPGAs have been used in such systems to aid with video
image manipulation (DSP)
Automotive Customer Presentation 16
Driver Support Systems:
Adaptive Cruise Control
• Adaptive Cruise Control or Collision Avoidance
systems
• Intensive Digital Signal Processing required
• Xilinx FPGAs offer extremely fast parallel digital
signal processing
• Parallel processing maximizes data throughput
– Support any level of parallelism
– Optimal performance/cost tradeoff
• FPGAs also support serial processing
• Standard Digital Signal Processors process

Soft Processor IP Cores
• Soft processor cores can be ‘owned’ by the customer
and used across many projects – never going obsolete!
• Peripheral can be added to make up only the functions
that are required – no wasted peripherals or logic gates!
• Code and peripheral ‘banks’ can be built up and used
across many projects over time
• Legacy code is not wasted saving time and money
Automotive Customer Presentation 25
X-by-Wire
• Replacing mechanical and hydraulic systems with
communications busses to control:
– Throttle, Steering, Braking, traction control etc
• Real-time response needed (paralleling the CPU? DSP Coprocessing? )
• Special interrupt/safety/task structure needed
• Hardware based designs are less prone to software based `bugs`
• New way of designing with FPGA based reconfigurable hardware:
– Prototype and testing with FPGAs - concept proving/quick changes
– Pre-production with low cost FPGAs (shrink/optimise designs)
– Production move to ASIC? (Depending on NRE charges and risk)
• Field/customer feedback on additional functionalities required can
be added during development and/or production

Introducing IQ Products
• Why IQ?
– New array of devices guaranteed over an extended
temperature range (-40 to 125°C)
– Consists of CPLD and FPGA families already available in
I Grade - and the addition of selected devices with an
extended temperature ‘Q’ grade option
– IQ - it’s the intelligent choice for Automotive designers!!
• For FPGAs Q grade means:
– -40°C to +125°C Junction Temperature
• For CPLDs Q Grade means:
– -40°C to +125°C Ambient Temperature
Ambient = the temperature of the air surrounding the device
Junction = is the temperature of the die in the package
Automotive Customer Presentation 29
Quality and Traceability
• Full mask set control
• Fab, assembly and test flow consistency
• Fully characterized to operate from –40ºC to
+125ºC (ambient temperature for CPLDs and
Junction temperature for FPGAs)
• All Xilinx production partner fabs are qualified to
QS9000
• PPAP data available
