Market Trends
Observations
Increased use of hook technology:
• ECU software providers inserting hooks within the ECU
software for stimulation and validation purposes
• OEMs engaging in more of the ECU software development
process requiring more hooks (function development,
software development, software testing, …)
Convergence of MCD and Prototyping solutions:
• MCD tools being used for prototyping, debugging and
validation of single ECU software functions
• MCD tools being positioned as prototyping solutions in
combination with ECU bypass functionality

What is EHOOKS?
Product Goal and Strategy
• Product Goal
• “Save you time by giving you the ability to implement ECU software
changes directly in the HEX & A2L files independently of the ECU software
development team”
• Target Market & Target Application
• EHOOKS was conceived as a rapid prototyping tool to allow bypass hooks
to be placed into the ECU software without the ECU software team
• During development other use-cases were
identified across the development cycle:
• Calibration, Function Development,
Software Development, Software Testing

What is EHOOKS?
Benefits
Immediately realise changes in the ECU software to
support your calibration, prototyping & testing needs
independently from the ECU software provider
Supported by major tier 1s which enables EHOOKS to
implement software hooks/changes with a high level of
quality and reliability
EHOOKS provides a seamlessly scalable solution:
• Work around minor software bugs with simple constant and
calibration hooks
• Use on-target bypass for more complex needs while eliminating the
hardware costs and ECU infrastructure needs of rapid prototyping
• For complex needs use the full power of high performance rapid
prototyping hardware.

Customer Quote
Eiji Hashigami – Honda R&D Automotive Centre
“We have been able to shorten the time formally required
for source-code modifications by the ECU supplier
for an ECU development project from several months
to as little as a few days by adopting EHOOKS”

What Does EHOOKS Do?
EHOOKS V2.0 Simulink Integration
• Simulink® Blockset and Simulink® System Target
allow easy and automated integration with
Simulink® for on-target bypass
• The Blockset provides:
• Simulink® driven configuration of EHOOKS
• EHOOKS ECU read and write blocks allows Simulink® model
to bypass ECU data
• EHOOKS ECU trigger block controls execution of model code
• The System Target supports:
• Automatic build integration with EHOOKS within Simulink®
• Automated generation of “glue-code” connects
Simulink®/RTW generated code to ECU infrastructure
• Automated data-type conversion, logical  physical
• Integration of “tunable” Simulink® parameters as ECU
calibration characteristics

What Does EHOOKS Do?
EHOOKS V2.0 ASCET Integration
“EHOOKS target” provides seamless
integration of EHOOKs into ASCET
• Map model elements to hooks (or use
automapping)
• Map ASCET processes to ECU tasks
• “one click” build from ASCET
 No change of ASCET model!
 Flexible use of service libraries
 Works with physical or implementation
model with ECU target quantization
Easy migration from
PC simulation ->
-> External Bypass ->
-> Internal Bypass ->
-> production code
