enable Rockley Photonics to achieve first-pass success
- Differentiated electromagnetic flow provided a 12X performance
improvement over legacy design flows
Cadence Design Systems, Inc. (Nasdaq: CDNS) today announced that
Rockley Photonics, a leading supplier of integrated photonic
solutions, has deployed a comprehensive set of Cadence® system
analysis and custom tools to design a state-of-the-art,
high-performance System-in-Package (SiP) for hyperscale data
centers. Using a broad suite of Cadence tools, Rockley Photonics
achieved first-pass success, accelerating time to market.
The Rockley Photonics device is a complex system-in-package
solution, comprised of discrete chiplets connected through a
high-speed 112G PAM4 serial interface. To successfully complete the
project, the Rockley Photonics design team needed a powerful,
comprehensive combination of Cadence system analysis and custom
tools, featuring the Clarity™ 3D Solver, Allegro® technologies and
the EMX® 3D Planar Solver; custom technologies including the
Virtuoso® RF Solution and Spectre® X Simulator; and the Quantus™
Extraction System for signoff. The Cadence design tools—across
chip, package, board and system—offer a tight integration that
doesn’t exist with other solutions on the market, providing Rockley
with a complete solution for system innovation.
The Rockley engineering team utilized the Clarity 3D Solver to
analyze system-level electromagnetics effects, a task they couldn’t
achieve with other tools. Using the Clarity 3D Solver from within
the Virtuoso RF Solution, Rockley Photonics’ engineers successfully
modeled coupling between the chiplets, the board, and the
high-speed transmission lines—including wirebonds—all the way to
the photonics chiplet, ensuring complete system performance. In
addition, the Cadence EMX® 3D Planar Solver provided a truly
differentiated electromagnetic flow that enabled Rockley Photonics
to demonstrate a 12X performance improvement over legacy design
flows.
“At Rockley Photonics, we routinely evaluate our system design
methodology so we can find ways to improve and enable our
engineering team to perform at their peaks,” said David Nelson,
vice president, IC design at Rockley Photonics. “By using the
integrated Cadence flow, we were able to capture a deterioration in
the 50-60GHz frequency range through its cross-fabric coupling
capabilities, whereas our previous flow, which utilized a
single-fabric approach, was not able to capture the deterioration.
In addition, the Clarity 3D Solver demonstrated impressive scaling
up to 128 CPUs, and the entire 100GHz cross-fabric design was
extracted in just three hours.”
The Cadence system analysis and custom tools support the
company’s broader Intelligent System Design™ strategy, providing
customers with an efficient path to achieve system innovation. For
