HIL - TEST AND SIMULATION

Customizable HIL test platform, created to support critical tests during development, validation and production processes of electrical and electronical components.

RTSTAND IS WINNER OF THE NATIONAL INSTRUMENTS TECHNICAL INNOVATION AWARD

„Because of RTStand we were able to detect a sporadic error we wouldn´t have found with the old test approach. This saved us a lot of money, as the failure has been

detected in a very early stage of development of our gateway.“

Thomas Richter, Project Manager at Continental™

If you are looking for a test platform which supports complex industry requirements or if you are simply looking for modules to be integrated in an existing test setup, RTStand is the HIL platform to choose. In recent years the complexity of E/E/PE systems increased, putting a greater emphasis on the testing requirements, such as ISO 26262 or LV124. RTStand was developed in order to cope with this complexity and to provide a flexible and innovative platform for testing.

Conventional test methods can lead to difficult to reproduce failures. Such testing systems achie-ve only an inadequate accuracy. Sporadic errors between the individual test steps are no longer detected, with the high risk of these errors to remain undetected. This does not only cost time and money to correct, but it can also lead to companies’ image loss and unpredictable damage costs.

Having long-time partnerships with big companies in the various industries, WKS Informatik noti-ced these trends and also the difficulties these companies have in order to comply with all these norms and developed the RTStand as an innovative HIL platform.

RTStand optimizes testing processes through:• Reliable detection and innovative analysis of very short sporadic errors • Driftless and synchronous monitoring of all inputs and outputs, including fieldbus signals • Faster and comfortable test development • Flexible and scalable definition of the hardware platform • Intuitive and customizable user interface

RTStand reduces the total cost of ownership through:• Immediate integration in the National Instruments™ world • Worldwide hardware component support by National Instruments™ • Modular and scalable software components • Continuous software maintenance • Based and developed on industry standards NI LabVIEW, NI TestStand, NI VeriStand

HIL Test PlatformsDue to its modularity and scalability, RTStand proved to be a solution for various industries and

testing systems, including embedded software validation using HIL simulation along with a platform for life-time and end-of-line tests.

The following 4 test platforms describe the diversity of areas of application that RTStand covers:

1. RTStand Automotive Test Platform Overall, ECUs are critical to the functionality of a vehicle and all of the bus traffic. It is important to test them in a variety of ways, according to industry requirements, so that all sporadic and short errors can be detected in a reliable way. Using the RTStand Automotive Test Platform, the overall process of testing and error reporting is being significantly simplified and accelerated.

3. RTStand LV 124 Test PlatformIn recent years, the automotive industry has been faced with technical challenges that had to com-

ply with various industrial norms. One of the most important of these norms is the LV 124, which was

drawn up by the representatives of automobile manufacturers like Audi AG, BMW AG, Volkswagen AG,

Porsche AG and others. LV 124 describes various electrical tests and their requirements. An innovative

modular hardware setup and two ready-to-use WKS Informatik GmbH products – the TubeAnalyzer

(www.tube-analyzer.com) and RTStand – are integrated in this test setup.

Features:• Support of LV 124 test automation (EA01-EA22) • Support of onboard supply system simulation. • Support of sporadic error detection within 10us. • Support of complete chain tool, including LogViewer and TestRun Generator.

4. RTStand Production Test PlatformProduction test systems are based on critical criteria such as product measurement traceability and reliability, product variant handling, fast and stable testing process in order to reduce test times and lower costs. RTStand Production integrates all these criteria in just one test platform and add its own top features for an innovative testing approach. Features:• Support of user management. • Support of database management, including scalable design and automated

measurement logging. • Support of reporting in various formats (*txt, *.csv, *.html, *.xml, *.atml). • Support of production key figures such as work shift management.

All platforms support native RTStand features.

Software ComponentsThe diversity of the platforms is also based on the modular software components, which through their scalability and flexible use are able to comply with the most difficult requirements.

RTStand - HIL test and simulation software components

User InterfaceThe user interface comes with a set of standard functionality, such as test overview, online reporting and report visualization, customizable panels - for individual customer needs -, user management (administrator, operator), database connectivity and editor option for test sequences.

Database Parameter & ResultsThe Database module provides a reliable solution for measurement data logging, limits loading, vari-ant handling and also integrates a measurement data visualization and analysis tool.

Test AutomationThe Test Automation core supports sequential and parallel testing of several DUTs in parallel, in-cludes a custom step type library for over 50 devices, climate chamber control and reporting in various formats (*.txt, *.csv, *.html, *.xml, *.atml and other on request).

Actuator – Sensor SimulationThe Simulation module can be used to interact with models from a variety of modeling environ-ments and programming languages and it can run compiled models created in any supported mo-deling environment as well as uncompiled models (.mdl files) created using MathWorks Simulink® software.

Error Analysis Reporting The Error Analysis reporting module is based on an innovative “3 Click” measurement data mining method, for a quick and easy error analysis. It provides logging in the industry standard format TDMS and integrates a fieldbus measurement data analyzer, a TDMS measurement data analyzer. The re-port visualization is integrated in the user interface.

The “3 Click” data mining method is a fast and comfortable way to find the desired measurement failures. From the displayed data in the user interface, until the actual logged error, you can precisely find the error cause with only 3 mouse clicks, as pictured below:
