You can use the Evaluate > Mass Properties to determine where the center of gravity is as long as you have the materials entered correctly. Then some simple hand calcs will let you know how it looks.
No simulation is needed. Are you familiar with the term "center of mass"? If not, no big deal. Just trying to figure out the starting point for this conversation.
Although not a guarantee, but a quick check is the "middle third rule".
If you're CG is not within the middle third of the width of your base (all around the vertical axis), then most likely you will tip over as stability is less.
The converse of this isn't true though.
It also depends on how your CG is above your base. The higher it is, the less stable it is.
