Hi Jeff,


You can go through below manual related to Modelsim as Modelsim and Questa is similar only different in features supported. In term of usability, this could be same. Below manual is related to object window. Is turn off and on the object window resolve the issue? Close it and go to view click object to on the window and see if it reflect any data objects.

    Thank you for trying but closing the window and reopening the window gives the same results. the compiler is optimizing out all the net so there is nothing to view? In the terminal window it says loading the optimized design, I do not know if this is related to the starter edition license, or if it is a configurable setting some where I can turn off or modify?
