    Simulink

    Simulink

    MathWorks

    Design and simulate your system in Simulink before moving to hardware. Explore and implement designs that you wouldn’t otherwise consider – without having to write C, C++, or HDL code. Explore a wide design space by modeling the system under test and the physical plant. Your entire team can use one multi-domain environment to simulate how all parts of the system behave. Package and share your simulations with collaborators, suppliers, and clients. Reduce expensive prototypes by testing your system under conditions that are otherwise too risky or time-consuming to consider. Validate your design with hardware-in-the-loop testing and rapid prototyping. Maintain traceability from requirements to design to code. Instead of writing thousands of lines of code by hand, automatically generate production-quality C and HDL code that behaves the same way as the model you created in Simulink. Then deploy it directly onto your embedded processor or FPGA/ASIC.

    Ansys Exalto
    Ansys Exalto is a post-LVS RLCk extraction software solution that enables IC designers to accurately capture unknown crosstalk among different blocks in the design hierarchy by extracting lumped-element parasitics and generating an accurate model for electrical, magnetic and substrate coupling. Exalto interfaces with most LVS tools and can complement the RC extraction tool of your choice. Ansys Exalto post-LVS RLCk extraction lets IC designers accurately predict electromagnetic and substrate coupling effects for signoff on circuits that were previously "too big to analyze.” The extracted models are back-annotated to the schematic or netlist, and support all circuit simulators. The proliferation of RF and high-speed circuits in modern silicon systems has raised electromagnetic coupling to a first order effect that must be accurately modeled to reliably achieve silicon success.

    Ansys Pharos
    Pharos combines Ansys' unparalleled EM engine capacity with a proprietary high-capacity circuit simulation engine to perform coupling analysis and provide ranking of potential EM crosstalk aggressors per victim node. By highlighting the most susceptible nets, designers can focus their design decisions to manage EM crosstalk on these nets and de-risk the design process. Pharos combines unparalleled extraction engine capacity with a built-in simulation engine to perform EM analysis and provide ranking of potential EM crosstalk aggressors per victim net. This allows designers to focus on the most critical nets in the design. Increasing design complexity, along with the broad scope of magnetic field interference, makes identifying all EM crosstalk susceptible victim/aggressor net pairs a very challenging, if not impossible, task.
