On-Target Testing in a Desktop Environment

Example ECU controller code developed with MotoHawk® Software

Example ECU controller code developed with MotoHawk® Software

LHP/DTE provides embedded systems engineers an environment to verify controls algorithms and other real-time software in a real hardware environment. Developers can run plant model software on the LHP/DTE to verify the real-time performance of the controls application on actual hardware. With this low cost desktop compatible package, individual engineers can have the convenience of performing model, controls algorithm, and software testing in the comfort of the office.

The DTE enables the embedded developer to do on-target testing with a simulated plant – in a convenient desktop environment. This results in reduced cycle time, comprehensive test coverage, and more effective verification and validation.

PLANT MODEL INTEGRATION

The DTE allows easy integration of your existing plant models so you can begin on-target testing right away. Alternatively, our product development team can custom build a model for your specific application needs.  LHP can provide customers with a quick-start reference model for automotive engine applications.
