Please post your model. There are several reasons why a scope may not show data and there is not enough information in your post for further guidance.

The " Buck Converter + Controls" subsystem is a Configurable Subsystem. Only one configuration can be active at a time. The scopes will not update in the inactive configuration. The schematic for each configuration can be accessed by the tabs on top of the schematic view. The default model settings has the “Averaged Buck Model + Continuous Controls” setting active.
