1.6.3.1. Editing Wire-Level Expressions

After you add a wire-level expression to an optional input port, you can add, edit, or remove wire-level expressions and connections in the Platform Designer GUI.
Follow these steps to edit wire-level expressions in the Platform Designer GUI:
  1. To specify a new wire-level expression, right-click an input port in the Hierarchy tab and click Add Wire-Level Expression. The Edit Wire-Level Expression dialog box appears.
  2. To construct the expression, drag operators or ports from the list of operators or ports, and drop them into the expression field. Refer to Wire-Level Expression Syntax for a list of legal operators.
  3. Click the text field at the top of the Edit Wire-Level Expression dialog box and press the Down Arrow key to enable the expression assistant. The assistant provides a context sensitive list of available operators at the cursor position.

    • Click an operator node to change the operator type.
    • Reorder nodes or move nodes between operators by dragging them.
