4.3.4.1 Installing a Node-Locked Disk ID License on Windows

Attention: A node-locked license does not support remote desktop login. Only a floating license supports remote desktop login.

To install a node-locked Disk ID license on Windows, perform the following procedure:

  1. Create a folder named flexlm on the c:\ drive and save the License.dat file in that folder.
  2. Open your Environment Variables dialog:
    1. Right-click Computer and select Properties. The System dialog appears.
    2. Click Advanced System Settings. The System Properties dialog appears.
    3. Click the Advanced tab.
    4. Click the Environment Variables button.
    5. In Windows Search, select Settings (Windows key +w) and search for Environment Variable.
    6. Double-click the environment variable. Your account opens the Editor.
    7. Open File Explorer, right-click This PC , and select Properties.
    8. Click Advanced System Settings, and then click Environment Variables.

    If the LM_LICENSE_FILE is already listed in System variables, perform the following steps:

      1. Select the LM_LICENSE_FILE, and then click Edit.
      2. Either add the path to the Microchip License.dat file after any existing variable value, separated with a semicolon (no space), or replace the existing value.

      3. Exit System Properties by clicking OK.

    If the LM_LICENSE_FILE is not listed in System variables, perform the following steps:

      1. Under System Variable, click New. The New System Variable dialog appears.
      2. In the Variable name field, type LM_LICENSE_FILE.
      3. In the Variable value field, type c:\flexlm\License.dat (or the path where you installed the License.dat file).
        Attention: The path to the installed license software is case sensitive; check for the case of the folder path in which the license is saved.
      4. Click OK, and then click OK again. The new environment variable is saved and you return to the System Properties dialog.

      5. Exit System Properties by clicking OK.

This completes the installation of the Libero SoC tools from Microchip, and those tools are now ready for use. If you plan to use the bundled third-party tools, such as Siemens ModelSim ME Pro and Synopsys Synplify Pro, note that in addition to the LM_LICENSE_FILE variable, which applies to all vendors, you can set the Synopsys license using two vendor-specific variables (see the following table).
Important: Libero SoC v12.2 or later does not impose any restrictions with the Synplify Pro tool. For Libero SoC v12.1 and earlier, Synopsys tools do not work beyond 50 miles or beyond the geographic locations. To remove the restriction, set the SCL_WAN_DISABLE variable (environment variable) to 1.
