Introduction

New Eagle has developed an automated testing platform (Raptor-Test) for Motohawk and Raptor™ models that greatly improves the effectiveness and speed of software verification.

Raptor-Test Overview (PPT)

  • Facilitates testing of model-based software against requirements through simulated hardware-in-the-loop (SimHIL)
  • Provides an intuitive graphical PC interface for authoring and executing test scripts over a USB-to-CAN interface
  • Encourages accumulation of verification infrastructure over project lifetime, allowing validation effort to scale in a write-once run-many fashion
  • Allows for increased confidence in production intent software releases.

The following figure shows an example of an Automated Test bench design to verify specific software requirements.

Motivation for Raptor-Test

How do you validate your production control software works properly prior to release?

How do you make sure that you don't break something you've already tested when you implement a new feature?

How do you assure that a service patch (bug fix) doesn't cause other issues?

Often, in a controls development program the software is validated empirically over time as the controls functionality is developed, debugged and calibrated. In the typical scenario, controls complexity grows over time, initially focusing on basic operation (does it run), and working on finer-grain features later such as diagnostic messaging and cruise control. The cruise control functionality is developed and tested when it is implemented & calibrated - then the team moves on to other features. The problem that is often encountered with this approach is that changes made to the software in later stages can result in defects in previously implemented functionality. Since the prior functionality was 'checked-out' at an earlier time it is assumed good until an issue manifests at a later point, sometimes in a fielded product. Another issue that arises is in making an update to a fielded product, sometimes after some months/years have gone by - will the change cause other issues? In the best cases, successful production programs take a more rigorous approach to production validation usually involving a lengthy written procedure (test plan) describing a manual checkout process executed against the production intent software/system. This procedure can be brought up at a later time and run against a software build to verify things work properly. Often this procedure is actually printed out and executed by an individual or team against the production intent vehicle to validate the controls software release. The individual(s) executing the test plan will work through the plan by driving the vehicle, pulling sensor wires and/or overriding values in MotoTune to exercise features and inject faults, and writing down pass/fail on the test plan. For a sufficiently complex system the execution of this test plan could take many days of focused effort. This is a time-consuming, error-prone, and expensive method of verifying the function of the production intent software. If you are creating production controls system - does this sound familiar?

Over the course of a decade of experience with this approach to system validation it never quite felt right. What we found was that there was not a good way to scale our effort in testing the system. As mentioned, a detailed test plan was created in the best cases but even then it was often relatively high-level, and would require significant effort to execute a lot of manual steps. What we were looking for was a way to test something and reuse our effort in testing it later, accumulating tests over time (building a test suite) so that we could gain increased confidence with the system functionality at each release. We needed a way to automate the manual steps so we could dive deeper in our testing to get better coverage. We needed a way to automate test execution so we could scale our validation development effort, allowing us to spend our validation time building the tests - not on running them.

This is why we built New Eagle's automated testing framework, Raptor-Test, which we hope you'll find is an excellent solution to the problem of validating your production controls.

Features

New Eagle's Raptor-Test tool provides a friendly interface between your PC and the rest of your testing setup, allowing you to set calibrations and overrides inside a running MotoHawk or Raptor model to verify the required software functions. The AT setup configuration can vary depending on the application's testing requirements. For some applications, the only required test components are: a PC to run Raptor-Test, a Kvaser cable for CAN-to-USB connection, and the Test Module. For other applications, Raptor-Test can interface with both a Test Module and a Coordinator Module via CAN to enable simulation of larger and more complex systems. The Coordinator Module typically runs a plant model, transmitting and receiving simulated sensor and actuation signals between the two modules. These signals can be CAN inputs and outputs or analog/discrete inputs and outputs between the modules. Raptor-Test reads the MotoHawk or Raptor probes to verify that the application software in the Test Module functions as required.

  • Scripted tests for reliable, repeatable testing
  • Run from the command line, MATLAB scripts, or with an interactive console.
  • Send and receive CAN messages
  • Set calibrations inside a running Raptor or MotoHawk model
  • Read probes from inside a running Raptor or MotoHawk model
  • Simulate behavior of the entire system:
    • Set override values for digital and analog inputs
    • Connect the unit-under-test to a coordinator module running a plant model of the rest of the system
  • Generates reports after each test run:
    • PDF reports for easy reading
    • XML reports for consumption by other software systems
  • Utilize Coordinator Module to send CAN messages
  • Verify CAN messages
  • Test CAN data time out
  • Verify logic (for example: Simulink model/State Flow) in the Test Module
  • Easy to use Graphical console for building and executing scripts:

Simulated Hardware In the Loop (SimHIL)

Simulated Hardware-in-the-Loop testing (or SimHIL) is a control systems validation strategy using simulated I/O to verify that the software functions match the application requirements. The goal of using a SimHIL approach is to validate software on the production hardware with physical signals to stimulate the module. Simulated I/O can include both CAN transmit and receive as well as analog/discrete inputs and outputs. There are a variety of strategies that can be used to test your software functionality, including setting of software overrides by Raptor-Test over the MotoTune protocol. This allows certain subsystems and states to be methodically triggered and tested. A Coordinator module can be utilized to simulate the analog/discrete I/O or CAN interfaces with other modules in the point of use application. The SimHIL testing setup can be easily tailored to each customer application based on the software requirements.

Difference between 'in-the-loop' Testing

  • Hardware in the loop (HIL) Simulation is a system test with part of the hardware components represented by complex mathematical models or controllers.
  • Simulated Hardware in the loop (SimHIL) Simulation is more like HIL, but 'the hardware components' are replaced by simulated models and controllers.
  • Processor in the loop (PIL) Simulation is with code running in the microprocessor on the target hardware or board.
  • Software in the loop (SIL) Simulation is with code running in the PC, no hardware involves.

USB license dongle

License Options

Customers can choose to purchase either a node-locked or dongle-based version of the Raptor-Test software. A dongle is a small USB device the contains the software license. The advantage of a USB dongle is that the software license can easily be passed from one computer to another. A node-locked license, on the other hand, lives on the computer itself and eliminates the need for any external licensing hardware. Node-locked licenses cannot be lost or come lost, which can be problematic for USB license dongles. While node-locked licenses can be transferred from one computer to another, the process is not as simple and fast as removing a USB dongle from one computer and plugging it in to another computer.

Software Updates

Customers have access to the latest software releases for a period of one year after their purchase. Each software release adds new features and address bug fixes. If customers wish to maintain access to new software releases after their first year of using the product, they can purchase a software maintenance license. Software maintenance licenses are valid for 1 year and can be renewed in perpetuity.
