Perform model export

How to perform a model export from System Architect application. The model export make possible to use a model outside from VISION environnment in order to use other kind of analysis tool. The model export is currently interfaced with SystemVue, VSS, Simulink and the Comlib2 module.

To begin this task, you will need:

The basic steps to perform a model export are:

  1. Choose the Template export palette. Drag and drop the 1x1 DC block from the palette window to the schematic window.

  2. In this step we customize the template in order to match with the device we want to export. In order to demonstrate the process we change the schematic in order to export a single HPA model with Rf and Pdc output :

  3. Double-click on the SIMCTRLR block to open the Parameters window. By default, the Simulation name is "sim0" and it is editable. In the Simulation mode tab, choose the Simulation mode by selecting CW simulation. Choose the Analyse type by selecting Nominal analysis. In the Solver tab, choose the Solver Type by selecting Algebraic solver I.

    Go to export tab and choose a model name (AMPHFLF) in addition of the simulation name (sim_CW_export).

  4. In this step we define a nominal condtition for the export process. Carrier frequency is choose as F0 = 0.83e9 and power is set to -30 dBm.

  5. The exported model can be parameterized. These parameters are added thanks variable bloc. For example, we can add a load dependency with the following var bloc which sweep the load value with a nominal value of 50.0 Ohms.

  6. The model can now be simulated and exported. In the menu bar of the workspace window, click on Simulate>Run simulation or on the shortcut . The output console is displayed:

    The blue line highlights the location of exported model. This folder contains all necessary data for beeing plugged into external simulator or into Comlib2 module Co-simulation with system modeler.
