Synopsys Inc. has rolled out its latest RSoft product line-up, which is a portfolio of software tools for photonic component and optical communication system design. The version 2015.12 of the Synopsys RSoft Photonic System Design Suite includes added features to expedite the design and fabrication of modern silicon photonics, photonic ICs and optical transceivers in data centre applications.

In addition, version 2015.06-2 of the RSoft Photonic Component Design Suite enables faster simulations of complex photonic component designs with flexible cluster licensing policies that take full advantage of multicore CPU architectures, stated the company.

The RSoft Photonic System Design Suite includes the OptSim digital signal processing (DSP) library that now supports transceiver design and bit-error-rate estimation based on m-PAM, an important multi-level modulation format for data centres and other short-distance applications; and the ModeSYS tool that now includes a model that combines multiple CW signals at the same wavelength into a single spatial field profile, enabling more efficient multimode co-simulation with Synopsys' CODE V software and the RSoft BeamPROP tool.

ModeSYS also supports user-specified launch conditions for large-core, step-index multimode fibres as either intensity or encircled angular flux (EAF), leading to more accurate results. In addition, ModeSYS includes additional plots that enable users to visualise the distribution of power changes at different positions within a multimode fibre, eliminating the need to run multiple simulations for each point of interest.

The OptSim Circuit tool includes an interface with Luceda Photonic's IPKISS design framework for photonic ICs. By adding the capability to export netlists that IPKISS can use to automatically synthesise a mask layout, OptSim Circuit further enhances the photonic integrated circuit design flow from system-level simulation to fabrication. OptSim Circuit also expands support for modern silicon photonic design and simulation by adding the latest version of the IMEC foundry process design kit (PDK), version 1.4.

The RSoft Photonic Component Design Suite version 2015.06-2 implements a policy for cluster licensing, enabling more flexible use of multicore CPU architectures. The licensing policy allows the RSoft simulation tools to fully utilise the computing power of a single machine for node-locked licenses and up to two machines for a network license. To use more than two machines for simulations, users can purchase additional, simulation-only licenses. Many of the RSoft photonic design tools leverage all available computing power to reduce the time of a single simulation, or to perform distributed simulations on different parameter sets. This allows, for example, RSoft FullWAVE simulation users to access all of their machines' computing power for many single FDTD simulations of photonic structures, or for one or more clustered simulations. The RSoft photonic design tools can also speed up the calculation of bi-directional scattering distribution function (BSDF) files with RSoft DiffractMOD or FullWAVE tools for high-accuracy optical surface modeling. As in previous RSoft releases, the number of concurrent jobs is unlimited, and therefore users can run multiple, simultaneous simulations, detailed the company.

Updates to Synopsys' RSoft product portfolio are available. Customers with a current maintenance agreement can download the software from the Synopsys website using their SolvNet account.
