Introduction to the New PDK for PIC Design
草榴社区 and are pleased to announce that a new, sign-off ready process design kit (PDK) based on Analog Photonics’ silicon photonics (SiP) design library is now available for the 草榴社区 PIC Design Suite, which includes the OptSim Circuit and OptoDesigner tools complemented with 草榴社区’ physical verification solution IC Validator.
草榴社区 is accelerating the adoption of photonic and PIC technologies with our comprehensive Photonic 草榴社区 design portfolio, which includes the RSoft? Photonic Device Tools, the Photonic System Tools, and the PIC Design Suite for photonic integrated circuit (PIC) design. Offering the industry’s only seamless design flow, the 草榴社区 Photonic 草榴社区 portfolio enables innovations in consumer and industrial communication, sensing, and imaging applications – from concept to manufacturing.
The PIC Design Suite offers photonic-aware physical layout capabilities enabled by support for foundry-specific PDKs. PDKs provide a crucial link between photonic circuit simulation and layout tools by supporting efficient design concept verification, signoff checks, and mask generation.
The AIM/Analog Photonics SiP PDK (AP_SUNY PDK) contains the building blocks for circuit simulation and layout generation as developed by Analog Photonics and mask layers, and design rules for the Multi Project Wafer (MPW) runs offered by at the SUNY Polytechnic Institute facilities. The PDK enables designers to develop PICs covering a wide range of passive and active photonic applications, including telecom, datacom, RF photonics, chem/bio sensors, and radar.
Version 3.5 of the PDK introduced statistical models for key passive and active components. OptSim Circuit natively supports Monte Carlo simulations with the implemented statistical models that are provided by Analog Photonics. By automatically calculating parameter variations and system performance metrics, OptSim Circuit has all the capabilities required to optimize PIC designs for manufacturing.
Features of the Updated AP_SUNY PDK
Key updates in version 4.0a of the AP_SUNY PDK include:
- Improved statistical device models for circuit simulation. Several device models have been improved, resulting in more accurate representation of chip behavior. The enhanced statistical modeling allows PIC designers to more accurately explore the impact of manufacturing variations on the performance and tunability of their PICs, thereby leading to more successful tape-outs and reduced design times.
- Addition of the design rule checking (DRC) deck for sign-off with IC Validator (ICV). ICV leverages EDA sign-off capabilities with dedicated photonics rules to improve DRC runtime significantly and shortening the design cycle closure to days instead of weeks.
Expert Opinions and Industry Impact
“Our PDK provides a large suite of components including, but not limited to, 100G capable modulators and detectors,” said Dr. Erman Timurdogan, Director of PDK Development at Analog Photonics. “With PDK v4.0, users have access to statistical models of these components based on the experimental data. The statistical models allow for prediction of the performance, yield, and corner analysis without spending the time and money to fabricate and test it.”
“The latest PDK from Analog Photonics provides enhanced predictive models for efficient design of SiP-based PICs,” said Tom Walker, group director of 草榴社区’ Photonic 草榴社区. “The statistical behavior models can be used in early product development phases for first-time-right design. OptSim Circuit users can optimize PIC designs using statistical models from the AP_SUNY PDK to support applications that use high-performance photonic ICs.”
