The global parameter list shows three columns displaying the names and the values of the parameters and the descriptions for them. To edit an item, perform a mouse click on it. Note that modifying a global parameter's name does not mean renaming it, but rather deleting a parameter and adding a new one. Therefore, if you attempt to edit a parameter's name that is used in your design, a warning message will be displayed that asks for a confirmation of the deletion of this parameter. To delete a parameter from the list, simply select the parameter's row and press 'Delete', or select delete from the context menu.
The block's parameter list is identical to the one contained in the Block Properties - Parameters dialog box. The parameter names, values and associated units are displayed. The names are fixed block properties and are therefore not editable. Values and units cannot be changed, either, if a reference block is referenced by the selected block and the associated property is affected by that reference. Otherwise, you may edit the values in the second column and select the units in the third column.
You may select the global unit (marked with a globe) or any local unit available.
