How to get the Altera design licenses? Is there an activation code needed?

For annual licensing, it is recommended to contact Altera directly, as the activation codes are typically associated with the Altera account used for licensing.

As an alternative, you can generate a 90-day no-cost evaluation license through the Altera Self-Service Licensing Center:
