© 2010 UEI, Inc. All Rights Reserved Overview The UEISIM is a Linux based system that runs Simulink models. UEISIM Desktop allows remote monitoring and parameter tuning while a model is running.

© 2010 UEI, Inc. All Rights Reserved Remote monitoring/Parameter tuning External mode: Use Simulink itself as client to connect to the UEISIM target. UEISIM Desktop: A client written in C#, C/C++ or LabVIEW can display the models signals and parameters without Simulink being installed. Signals and parameters are also accessible via a web page.

© 2010 UEI, Inc. All Rights Reserved Extra features (UEISIM desktop only) Remotely start/stop simulation Host PC client can start or stop simulations remotely Timing statistics: Average simulation step execution time Minimum step execution time Maximum step execution time Model execution time

© 2010 UEI, Inc. All Rights Reserved Signal Monitoring A model automatically publishes all exported signals under the name: /model_name/block_name/signal_name To export a signal, right-click and set Storage Class to Exported Global

© 2010 UEI, Inc. All Rights Reserved Parameter tuning A model also publishes all tunable parameters under the name: /model_name/block_name/param_name For example the constant block value parameter is tunable:
