Most Arm commercial tools are license managed. Arm is migrating to user-based licensing (UBL) which greatly simplifies license configuration. It is available for Arm Success Kits as well as Arm Development Studio .
Success kits are available as Hardware Success Kits (HSK) or Software Success Kits (SSK). See the table below for tooling provided. SSK is a subset of HSK.
With UBL, you have unlimited access to all components in the success kit you have enabled. The license is cached locally for up to 7 days, enabling remote or traveling users to access tools without connecting to their license server.
Starting any UBL enabled tool when the server is available will renew the license for 7 more days. This renewal attempt is performed once per 24 hours.
If the license is not renewed within 7 days, it is automatically returned to the pool of available licenses. When you next use a UBL licensed tool, it will automatically attempt to check out a new license.
User-based licensing can be managed with:
LLS), an internally managed license server, likely only accessible from your internal network or VPN.CLS), a license server managed by Arm, accessible from anywhere.Legacy product versions do not support UBL licensing and use FlexLM floating licensing instead. See the below table.

[1] Arm Development Studio versions indexed with letters after the period are for those users with access to non-publicly announced IP.
[2] A license to run pre-built platforms, including Fixed Virtual Platforms, is provided with SSK. HSK license is necessary to build virtual platforms.

, which may also require a
