To get started with Simplicity Studio® 5 (SSv5):
You do not need hardware to install SSv5 and the relevant software packages or, for 32-bit devices, to explore the project configuration interface for a particular SDK. However, having your target hardware connected during installation ensures that your SSv5 installation is configured precisely for your environment.
You should also have an account set up in the Silicon Labs Customer Support Portal. Access to some software packages is controlled by your customer profile.
See Prerequisites for more information.
If you have features or functions that are provided as an SDK extension, you need to install it separately after you have installed the main SDK. See Install SDK Extensions for more information.
