MOUNTAIN VIEW, Calif., Dec. 11, 2015 — Synopsys Inc. has announced new versions of its RSoft photonics component and optical communications system design software. Version 2015.12 of the RSoft photonic system design suite includes new features to accelerate the design and fabrication of silicon photonics, photonic integrated circuits and optical transceivers in data center applications. Within the software suite, the OptSim digital signal processing library now supports transceiver design and bit-error-rate estimation based on the m-PAM modulation format for data centers and other short-distance applications. ModeSYS also supports user-specified launch conditions for large-core, step-index multimode fibers as either intensity or encircled angular flux. The OptSim circuit tool includes a new interface with Luceda Photonic's IPKISS design framework for photonic integrated circuits. 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. A new licensing policy allows the RSoft simulation tools to fully use the computing power of a single machine for node-locked licenses and up to two machines for a network license. The tools can also speed up the calculation of bidirectional scattering distribution function files with RSoft DiffractMOD or FullWAVE tools for high-accuracy optical surface modeling. The number of concurrent jobs is unlimited, and therefore users can run multiple, simultaneous simulations.
