Sphinx
Sphinx for SignOff is a Frequency Domain Signal and Power Co-Simulator. Through careful discretization of the Helmholtz equation, its conversion into a circuit representation and through proprietary transmission line referencing methods, Sphinx for Signoff offers a solution that captures the physical phenomena occurring when high speed signals propagate on interconnections in the presence of power distribution networks. It captures the lateral coupling in layered stacks, the vertical coupling through apertures and the effect of referencing on signal lines. This method is known as Multi-layered Finite Difference Method (M-FDM).
IdEM Plus
IdEM has strong links with world leading research groups in the field of modeling and simulation. This is a guarantee of fast and direct technology transfer. IdEM uses best-in-class algorithms to build macro-models, including a proprietary data causality certification module based on Hilbert transform, highly scalable rational fitting modules enabling unlimited port counts, and top-class passivity enforcement schemes for safe and stable transient simulations. If a user has purchased BOTH Sphinx and IdEM Plus licenses, Sphinx users have a seamless GUI interface to IdEM Plus. IdEM Plus is a user friendly tool for the generation of macro-models of linear lumped multi-port structures (e.g., via fields, connectors, packages, discontinuities, etc.), known from their input-output port responses. The raw characterization of the structure can come from Sphinx’s frequency domain simulation. The resulting models are cast in common SPICE formats for the system-level simulations required in your design flow. Thus, IdEM Plus enables SPICE processing for any kind of linear structure, component, interconnect or package.
Sphinx DC
Sphinx DC allows Sphinx users to continue their analysis down to DC, computing IR voltage drops and identifying current choke points, all without leaving the familiar Sphinx environment. The simple, easy to use GUI, console, scripting and batch mode are all available to the Sphinx DC user, and DC analysis can be run in parallel with AC analysis for work flow efficiency. Sphinx DC provides the user with both graphical and spice circuit outputs for further analysis.
