Silicon Photonics

ADS 2026 enhances the Photonic Designer that includes photonic schematics, models and layout. It is the industry’s complete silicon photonics chip design workflow integrated into a single design environment to accelerate the development of Photonics IC (PIC). It cuts the tedious and error prone manual integration of multi-vendor tools and data. PIC designers can now productively focus on the design and validation of optical, electrical-optical (EO) and optical-electrical (OE) circuit layouts to meet performance, yield and reliability specs

Licensing

  • FlexNet Licensing Module: Version v11.19.7
  • Keysight EDA Licensing Software: Version 2025.04
  • License Codeword Version: 2025.02 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 at: [email protected] 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.
