Simscape and SimElectronics will allow you to model analog electronics and electro-mechanical sytems at a system-level. If you want detailed SPICE-level simulation, this isn't the right tool for you. However, in SimElectronics there is some (limited) functionality for importing SPICE netlists:

Have a look at the following demos to give you an idea of Simscape and SimElectronics capabilities:
