Using SysPhS and OpenModelica with Enterprise Architect

Overview

Learn how to simulate SysML using the OMG SysPhS specification that supports simulating models in both OpenModelica and Mathworks' Simulink.

In this webinar we examine the construction and simulation of a common digital electronic circuit - a flip-flop counter - used for halving a digital clock's output frequency. All the runtime variables are defined in the Enterprise Architect model using SysPhS, ensuring that it can be simulated and viewed in both OpenModelica or Simulink.

In this webinar, you will learn how Enterprise Architect can be used to:

Set up SysML simulation using SysPhS for common integration with OpenModelica and Simulink.
Run a simulation in OpenModelica and view the corresponding plots.
Debug and understand simulation results.

Questions & Answers

What version of Enterprise Architect is required to use the features shown in this webinar?

This webinar was conducted using the Enterprise Architect 15.2 Beta.

Please visit the following for more information:
Enterpise Architect 15.2 landing page

Are there any other SysPhS examples or resources available?

In the example model supplied with this webinar there are two models:

the digital Flip-flop model
an analogue Operational Amplifier model (OpAmp)

For the analogue model, there is a video covering this on the 15.2 beta page:
Using SysPhS for model based simulation

Is it possible to 'reverse engineer' an Open Modelica model into Enterprise Architect?

The primary flow is from a SysML model as part of an MBSE design. So the flow is from the model to the plot. However, in theory, a reversal using Enterprise Architect’s grammar parser could be used. It may be considered as an option in the future.

With this working on Modelica, is this also possible using Wolfram SystemModeler?

No. The code generated is compatible with the Modelica standard and should work with any client application that supports Modelica directly. We have briefly tried this with Dymola and Wolfram SystemModeler and these both appear to be compatible.
