How do I enable my 30-day Eval license for CNN IP for UltraPlus?

First you must have Lattice Radiant license. You can get it from http://www.latticesemi.com/Support/Licensing#radiant.A Lattice web account is required for this.License paths are saved in environment variable LM_LICENSE_FILE.
If you received the 30-day license for CNN IP, these are the actions required.
1. Change file name to license_cnn.dat (or any name of your choice to be able to easily identify license)
2. Save this file to the license directory of your Lattice Radiant installation (i.e. C:\lscc\radiant\1.0\license)
3. Edit the Environment Variable LM_LICENSE_FILE to point to the proper
file (i.e. C:\lscc\radiant\1.0\license\license_cnn.dat). Go to Registry Editor (in Start Menu, type regedit), find
LM_LICENSE_FILE, right click then Modify or Control Panel -> System and
Security -> System.Then on the left
pane, click Advanced system settings. In Advanced tab, click Environment
Variables. You should see the LM_LICENSE_FILE for edit. Use semicolon to
separate paths or click New to add new path.
Now, you should have both Radiant and CNN licenses in your environment variable.
