Parameter Sets

Components can be assigned parameter sets through the Parameter Sets dialog to the upper right of the screen. It is one of two available docked tabs, the other being Parameters.

Having multiple parameter sets enables testing of the model under various assembled groups of conditions. These sets can be selected and applied during simulation, so users can view the models' responses to these changes. 

• One parameter set defines one set of working conditions for the model. See below, in the columns labeled Set 1, Set 2, etc.
• Users define these conditions in advance through using multiple parameter sets, one set for each group of conditions.
• Then, on the fly, users can change sets at any given time to alter the parameters being applied, as a whole and at once.
• This can be used to manipulate a model's conditions, or simply to test the model under various sets of conditions.

To add/edit a parameter set:

• Select a component on the canvas and click the Parameter Sets tab. You'll note that by default there is only one set of parameters. 
• Click the + sign to the top of the right side of the table. A column labeled Set 1 with Id 1 appears.  
• Enter the capacitance value (for example, or the parameter being modified) for the first set.
• Repeat the previous two steps for every set of parameters you'd like to add. 
• To create a new parameter set automatically, enter a value in a new, unused column to the right of the table. 

NOTE: If parameters fall outside of acceptable values, they are refused.

Repeat the following steps for each component or block:

• Select a new component on the canvas.
• Then enter values, as below, for each parameter you'd like to modify.
• Repeat the previous two steps for every component to which you would like to add parameter sets.

To re-order columns:

• Click and drag a column to the left or right as desired once the hand icon has appeared.
• Note that the hand icon is outstretched after selecting the column, and clenched once the column is clicked and dragged.
• A grey vertical bar and outwards-facing arrows appear, showing where the column is to be dropped.

To insert columns to the left or the right, or to delete columns:

• Right-click the table cells and select the desired option from the contextual menu.

To reference parameter sets by name in HYPERSIM or RT-LAB:

• Sets can be renamed. These names are significant, as they can be referenced from within HYPERSIM and RT-LAB to change an active set while the simulation is running. 
• The user can, for example, through a dialog box, swap out parameter sets, knowing how these sets have previously been set up.
  
• For more, see the HYPERSIM and RT-LAB documentation.

To reference parameters set Set Ids by name in HYPERSIM or RT-LAB:

• Set Ids are also used in HYPERSIM and RT-LAB to control the active set, however through a signal name in the model, and not through a dialog box as outlined above.
• Thus if the current value of the signal is 1, users can set the active set to the one with Set Id = 1. 
• Changing a signal via its Set Id changes the operating conditions of the model by linking the corresponding parameters Set ID on the fly.
• The resulting signal, then, following the change and depending on its contents (values that vary in real-time), drives the active sets.
