en.Wedoany.com Reported - Keysight Technologies has announced support for GlobalFoundries' silicon photonics process technology in its ADS Photonic Designer, expanding its foundry ecosystem for photonic integrated circuit (PIC) development. This update enables designers to transition from PIC design to electro-optic-electro system simulation within a single environment and evaluate optical link performance prior to tape-out.

Silicon photonics is increasingly used in data centers, AI infrastructure, and optical communications, where engineers need to verify not only PIC designs but also system-level behavior. In many workflows, engineers typically use different tools for PIC design and system simulation, increasing complexity and pushing verification to later stages of the development cycle.

Keysight's PDK for ADS Photonic Designer links PIC design with system-level electro-optic-electro simulation. Engineers can design photonic circuits on the GlobalFoundries platform and then evaluate optical link behavior in the same environment, including eye diagrams and signal integrity metrics such as Transmitter Dispersion Eye Closure Quaternary (TDECQ). The PDK uses physics-based models consistent with GlobalFoundries' silicon photonics process, supporting correlation between simulation results and manufactured devices, while system-level analysis helps verify channel link performance.

PIC and system-level verification are particularly critical in high-speed optical interconnect development and late-stage design phases where both photonic and electronic performance must be evaluated. Engineers developing optical transceivers and co-packaged optics can also use Keysight's FlexDCA oscilloscope software during the design process to compare simulation results with measurements.

The PDK's physics-based models align with GlobalFoundries' silicon photonics process, allowing teams to start designs without creating component libraries from scratch; FlexDCA measurement and TDECQ analysis capabilities help compare design simulations with test results before tape-out; earlier evaluation of PIC performance impact on optical links during architecture development can reduce subsequent redesign efforts.

The GlobalFoundries CLO PDK for ADS Photonic Designer is now available.
