It then discusses the many new features available with the recent 2020 R2 release including spatial correlations in statistical circuit analysis. This webinar starts with an overview of Ansys Lumerical’s system level tools with special focus on the statistical support available with INTERCONNECT and CML Compiler. With its partners, Ansys continues to help its customers achieve their manufacturing goals with statistical support for its PIC workflows including corner and Monte Carlo analysis The previous section demonstrated the stability ofthe HD models under test to a very smooth excitation with a priori knowledge of the excitation in a Thevenin circuit equivalent.
FDTD SPICE SOFTWARE
Ansys Lumerical’s CML Compiler automates the creation, maintenance and QA testing of compact model libraries (CMLs) for both the INTERCONNECT and the Photonic Verilog-A platforms.Īnsys Lumerical is uniquely positioned in the photonics ecosystem to provide PIC designers with complete workflows from “concept to silicon” with its broad set of software tools and foundry partners. An hybrid method (FDTD with SPICE) has also been used for lossless transmission lines excited by a nonuniform incident electromagnetic field 47, the FDTD. equivalent circuits into the FDTD-EM lattice and SPICE models. Moreover, three techniques, which map a lumped circuit into FDTD cells as a wire, surface or volume structure respectively, are thoroughly studied.
FDTD SPICE SIMULATOR
Photonic Verilog-A enables EDA-style simulation when used in conjunction with industry’s leading SPICE/Verilog-A simulators, facilitating the design and implementation of electronic-photonic integrated systems. This method adopts the finite-difference time-domain (FDTD) algorithm for the EM simulation, the sophisticated equivalent models in a general circuit simulator SPICE for the circuit simulation, and hybridizes the FDTD and SPICE by using the equivalent current source (ECS) approach. INTERCONNECT is a dedicated PIC design environment and simulator, with an extensive list of predefined elements including System Library for optical communications applications and Laser Library for a broad set of laser applications.

It offers two simulation platforms - INTERCONNECT and Photonic Verilog-A. In high-speed signal transmission, understanding transmission line behavior is imperative to achieving proper impedance matching and proper termination to minimize loss stemming from reflections, as well as to maximize signal integrity. Ansys Lumerical offers all the tools needed for photonic system level simulation and interfaces to EDA tools for complete chip design.
