The procedure for requesting AWR support has changed. Please read all about
the new AWR product support process.
Nonlinear simulations, measure voltage, current, power at any node including hierarchy without adding meters. Meters were required but many versions ago, so if you are still using them, you don't have to.
For any nonlinear measurement, there is a pull-down selection for common measurement locations and then an ellipsis to allow you to choose more locations
Then a new view will open that contains a picture of the Data Source. From this view, you can select the location from the left lower pane. The numbers indicate node numbers. Whatever is selected in the list will be highlighed on the circuit. The upper left pane allows you to navigate hierarchy.
