By default, when you use the tuner in the NI AWR Design Environment, schematic/system diagrams update and graphs update at each point the tuner uses.   In this mode, layouts do not update until the tuning operation is done.  There are additional modes for the tuner.

• Hold the CTRL key to update layout at each point. 
• Hold the SHIFT key to get updates when you release the mouse. 

Please see  Tuning for documentation on using these modes.

Example Demonstrating the Differences

Click below to see what normal tuning looks like. Notice the graph traces update but the W parameter and layout do not update until the tuning process is done.

Click below to see what tuning with the Ctrl key held down. Notice the graph traces,the W parameter and layout update at each tuning step.
