16.8 Using NetlistViewer (non-MVN) with Timer

To view and trace timing paths, use NetlistViewer with Timer.

To trace paths using NetlistViewer and Timer, perform the following steps:
  1. In Designer’s Design Flow window, select NetlistViewer.
    Note: To start NetlistViewer, the design must be compiled. If the design is not compiled, Designer prompts to compile it. NetlistViewer then starts and displays the netlist.
  2. In Designer's Design Flow window, click Timer . The Timer window opens, as shown in the following figure.

  5. Select the path that you want to expand.
  6. Double-click the path to expand it, or select Edit > Expand Paths. The Expanded Paths window opens and displays the Expanded Paths grid and a graphical representation in the Graph window, as shown in the following figure.
