PIC Design Suite

From concept to manufacture. One integrated flow with one support channel.

Synopsys PIC Design Suite with OptSim Circuit and OptoDesigner Tools

Synopsys is driving the photonic integrated circuit (PIC) revolution with design automation solutions for a wide range of application requirements, from data communications to sensors and biomedical devices.

Synopsys’ PIC Design Suite – photonic integrated circuit design software that includes the OptSim Circuit and OptoDesigner tools – offers a seamless PIC design flow from concept to manufacturable design, as well as access to a single, world-class support channel.

  • The PIC Design Suite’s design, simulation, and mask layout implementation capabilities for PICs provide a modular and synergistic integration towards first-time-right fabrication.
  • OptSim Circuit supports the design and optimization of PIC functionality.
  • OptoDesigner has photonic-aware physical layout capabilities to synthesize PIC layouts for fabrication.
  • The PIC Design Suite enables both PDK-driven and custom design, and supports the widest portfolio of foundries offering MPW access. The PIC Design Suite integrates with the RSoft Photonic Component Design Suite, Synopsys HSPICE, and Sentaurus TCAD tools for cohesive, precise simulations of photonic and optoelectronic components and provides co-simulation of electronic and photonic circuits.

What's New

The latest releases of the RSoft and OptoDesigner tools create an even more seamless flow from photonic device development and PDK creation to PIC circuit design, layout implementation, and verification.

We are excited to introduce the first Photonic LVS flow in the industry with OptSim Circuit, OptoDesigner, and IC Validator. To close the loop between design intent at the circuit level to manufacturable mask designs, this new feature automates the reconstruction of the netlist from OptoDesigner-generated mask data and compares it with IC Validator to the original intent captured with OptSim Circuit. The flow reduces human errors and time-consuming manual checks.

Release 2019.03 Highlights

OptSim Circuit

OptSim Circuit is an ideal platform for modeling and optimizing performance of PICs at the system level. The interface between OptSim Circuit and OptoDesigner provides users with a seamless path from PIC design to mask layout.


With a flexible and integrated environment focused on manufacturable designs, OptoDesigner enables efficient, high-quality PIC device development.

Key capabilities include:

  • Photonic chip and mask layout
    • Powerful scripting capabilities support creation of the design intent; automation tools transform the design intent into a mask layout
  • OptoDesigner advanced connectors and autorouting
    • Phase-aware waveguide generation using computed optical lengths from foundry-specified data
    • Automatic phase-insensitive waveguide and metal routing for assembling complex circuits
  • OptoDesigner simulation modules
    • Simulation engines used to optimize layout for phase, polarity, dispersion, loss, etc.  
    • Also used to analyze impact of temperature and lattice stress on performance of given layout structures
  • Photonic design verification
    • Design rule checking enables verification of design and manufacturing rules for photonic curvilinear layouts
