Teraspeed - Electromagnetic & IBIS Modeling

AccuModel™ Electromagnetic and Measurement Based Modeling

Teraspeed® consultants continuously evaluate and characterize modeling methods for use in advanced Interconnect Engineering. With our AccuModel™ process, we utilize state-of-the-art field solvers and simulation software, in conjunction with our own validations against theory and practice. We model, simulate and measure to understand the limits of approximations in our tools and their effect on system performance. Our modeling capability includes, but is not limited to:

Measurement Based AccuModel™ IBIS Modeling- Using advanced equipment, techniques, software and a proprietary process, Teraspeed® Labs provides the most accurate IBIS models in the industry. Call (503) 430-1065 for more information. Teraspeed® IBIS Models
AccuModel™ Semiconductor Package Modeling - Using 2D, 3D and full-wave field solvers, Teraspeed® consultants develop models of package sections for characterization, optimization and system simulations. We utilize modeling technologies targeted to the speed or bandwidth required by the specific design and continuously validate our models with measurements at Teraspeed® Labs.
AccuModel™ 3-D Structure Modeling - Using 3-D and full-wave field solvers, Teraspeed® consultants develop models of the structures used in high-performance interconnect. Complex connectors, packages, pads, escape patterns, SMA launches and via transitions are modeled to the bandwidth required for each specific application and can be provided in Hspice compatable and S-parameter formats.
AccuModel™ 2-D Structure Modeling - For planar structures, we employ 2-D field solvers to extract RLGC parameters as a function of frequency for the modeling of lossy transmission lines. These models, in Hspice W-element table model format, have been validated for accuracy in modeling the latest in differential communication interconnects at 3.125, 10 Gbps and 40 Gbps data rates. We have experience with the modeling, measurement and correlation of various substrate materials, including: FR-4, FR-406, Nelco 400-13SI, Gtek, and Rogers 4350, Pyralux FR, Pyralux AP and LCP.
AccuModel™ Measurement Based Modeling - Teraspeed® Labs provides the experience to develop accurate characterization boards for the study of macro or micro details of a system. We provide fixturing for precise VNA and TDR based measurements of insertion loss, return loss, crosstalk, impedance and de-embedded parameters for transmission lines, vias, connectors and packages, along with accurate measurement of material characteristics.
