ECU Rapid Prototyping Software
ATI offers an innovative, patented software-centric method for rapid prototyping production ECUs with its sector leading technology. Functioning as an extension of VISION Calibration and Data Acquisition Software, the primary benefit of rapid prototyping software is that it allows users to internally bypass Read-Only control variables in the ECU’s RAM with calibratable parameters. With ATI's rapid prototyping users can bypass internal variables and create new functionality without pre-defined ‘hooks’ or preparatory code with ATI’s patented rapid prototyping solution for pre-production ECUs
ATI offers multiple categories of Rapid Prototyping Technology:
- No-Hooks Toolkit - Allows users to bypass control variables in the ECU’s RAM that are normally only viewable or measurable
- Advanced No-Hooks Toolkit - extends it to allow ECU functionality to be modified by user defined functions, without access to the original ECU source code or the need for other applications such as MATLAB/Simulink.
- OnTarget Toolkit - Allows bypassed variables to be integrated with model outputs into the production ECU executables without any modifications to the ECU source
- Model Browser - Provides a sophisticated user interface of Simulink models from within VISION software to enhance OnTarget or xPC Target calibration and data acquisition functionality.
- Model Based Calibration (VISION MBC) Toolkit - MBC is the implementation of a Model-in-the-loop (MIL) system. The MathWorks’ tools, MATLAB® and Simulink®, provide the modeling environment and VISION MBC provides the ‘in-the-loop’ capability, integrating VISION with the model as it runs natively within the Simulink® environment.

No-Hooks
No-Hooks
With only the information needed for traditional calibration and using an ECU interface, Base No-Hooks allows the user to control and adjust ECU controlled global RAM variables in the ECU. Use Base No-Hooks to select variables and convert them to calibratable variables and use ATI's VISION Software interface to easily make changes. Simplify and expedite tasks, enable creativity, and lower costs using ATI’s Base No-Hooks.
Features:
- Lower cost than hardware solutions
- Bypass variables with calibratable parameters
- Rapid prototyping functionality is independent of the ECU interface
- Conduct rapid prototyping on production intent hardware, providing functional confidence that will translate to saved development time and money
- No need for original ECU code, eliminating delays and cost for iterative changes between groups or companies
- Allows calibration, data acquisition, post analysis and software rapid prototyping in the same application
- Use the ECU hex image generated by No-Hooks to flash as many targets as needed
Advanced No-Hooks
Advanced No-Hooks
Accurate Technologies’ Advanced No-Hooks is based on ATI’s patented No-Hooks technology, extending it to allow ECU functionality to be modified by user defined functions, without access to the original ECU source code or the need for other applications such as MATLAB/Simulink.
Advanced No-Hooks shortens the development cycle to bring products to market faster. Prototype runs on production intent ECU which corresponds in every way to improving the success of the final product. The Advanced No-Hooks bypass runs in-line with the rest of the original code on the target ECU. There is no need for data transfer protocols or the resulting delays for running the bypass on external devices, which translates into virtually no latency
Features:
- User defines a function in C like syntax for the dynamic hook value using VISION data items, constants, and Advanced No-Hooks variables
- No-Hooks DLL creates relocation and trigger code
- Function Library and function editing with syntax highlighting
- Requires only No-Hooks DLL for target CPU
- No need to implement “hooks” in advance of using Advanced No-Hooks
- Implementation of Advanced No-Hooks can be performed at any time in the development process
- No re-compiling of the original source code is needed
- Simultaneously view the original variable value along with the bypassed value and values declared in the Advanced No-Hooks functions
- No additional hardware or software tools other than ATI’s VISION with No-Hooks and Advanced No-Hooks
- All ATI’s Rapid Prototyping products work seamlessly with the calibration, signal monitoring, data acquisition, and post analysis capability of the VISION Calibration and Data Acquisition Software
OnTarget
OnTarget
OnTarget enables the expanded capability to add custom model based control algorithm code to replace the existing ECU code for calculating selected RAM variables on the ECU under test, also called the Target. In the No-Hooks tradition, there is no need for access to or modification of the ECU source code; all that is needed is the ECU executable and description files.
OnTarget was designed to make use of Simulink® models to develop these alternative control algorithms. Simulink is a platform for simulation and Model-Based Design from MathWorks. OnTarget includes the appropriate Simulink libraries (block sets) and target build files for generating C-code using Simulink Coder™ (formerly Real-Time Workshop®) and compiling the code with various compilers (like the free ATI GNU compilers).
Features:
- All the features of No-Hooks Rapid Prototyping
- Bypass variables with outputs from a Simulink® model, allowing the addition of an entirely new control algorithm to the existing ECU code without modifying the original ECU source code
- In many cases can use a free ATI GNU compiler
- Purchase only the functionality needed
- Cost effective for fleet and durability testing of new algorithms
- OnTarget is ideal for the prototyping and testing of new closed-loop functions and Function A/Function B comparison testing
- Both the base strategy and the bypass model are calibratable simultaneously
- Harnesses the modeling abilities of Simulink combined with the calibration support of VISION
Model Browser
Model Browser
ATI's Model Browser provides a sophisticated user interface of Simulink models from within VISION software to enhance OnTarget or xPC Target calibration and data acquisition functionality. The Model Browser Screen Object provides a real-time view of the Simulink model in terms of data and control flow rather than the typical list of numbers and enables graphical measurement and calibration of the model during development and testing.
Key Features:
- View and calibrate the function of the entire system from VISION including the ECU, the new model (internal to the ECU via OnTarget or external via the xPC Target Software), and data acquisition devices may be viewed and calibrated
- Show live data on the signal lines and parameter values on the blocks displayed in the model
- Add constants, curves, maps, and other calibratable data items from the blocks to the familiar calibration screen objects of VISION
- Navigate the model by clicking on subsystems through the model tree view or through the model subsystem views (similar to Simulink)
- No need for the MathWorks® MATLAB® or Simulink® softwares
Model Based Calibration
Model Based Calibration
Model Based Calibration (MBC) Toolkit integrates its functionality into MathWorks MATLAB®/Simulink® for “Model in the Loop” (MIL) simulations. MBC brings the benefits of VISION's easy to use Calibration and Data Acquisition features to advanced control system designers working on MIL simulations, enabling control algorithms to be developed exclusively via PC based simulation.
MBC can quickly instrument a Simulink MIL system and makes it easy to control and calibrate in VISION as it runs natively within the Simulink® environment. Similar in operation to OnTarget software, MBC enables testing, development and verification tasks to be made without requiring an ECU or external hardware.
Key Features:
- Integration to existing models within VISION by linking the model running within the Simulink® environment to the VISION computer.
- Post model integration common device interface. The distinction between this virtual device and all other physical devices is transparent to VISION.
- Powerful display of signals and calibration parameters including user configurable strip charts, recorders, lookups, dials and gauges are available.
- Users can view models in VISION along with dynamic data overlays with the optional VISION Browser for Simulink® Models Toolkit.
