Licensing

• FlexNet Licensing Module: Version v11.19.8.5
• Keysight EDA Licensing Software: Version 2026.02
• License Codeword Version: 2026.02 or higher
• Refer to the codeword compatibility table here:
• MAC Address Requirements: Licenses must now be tied to the physical MAC address of the PC, Licenses can no longer be bound to aliased, virtual, or removable Ethernet devices, such as USB network adapters or docking stations.

If your current license configuration is impacted by these changes, we encourage you to contact Keysight EDA Business Support or get in touch with your local Keysight EDA Field Representative. They will assist you in initiating a License Transfer Agreement to transition your license to one tied to a physical MAC address.
