ANSYS Q3D Extractor Capabilities

Fast, Accurate 3D Parasitic Extraction

ANSYS Q3D Extractor includes several solution types for parasitic extraction of electronic packages, touchscreens and power electronic converters.

3D Quasi-static Field Solver
ANSYS Q3D Extractor contains an advanced quasi-static 3D electromagnetic field solver based on the method of moments (MoM), and is accelerated by the fast multipole method (FMM). Results include proximity and skin effect, dielectric and ohmic loss, and frequency dependencies. Q3D Extractor easily and quickly provides 3D extraction of resistance (R), partial inductance (L), capacitance (C) and conductance (G).

2D Extractor: Cable and Transmission Line Field Solver
ANSYS Q3D Extractor includes a powerful quasi-static 2D electromagnetic field solver that uses the finite element method (FEM) to determine the per-unit-length RLCG parameters for cable models, transmission lines, characteristic impedance (Z0) matrices, propagation speed, delay, attenuation, effective permittivity, differential and common-mode parameters, and near- and far-end crosstalk coefficients.

Automatic Adaptive Meshing

Automatic adaptive meshing techniques require you to specify only geometry, material properties and the desired output. The meshing process uses a highly robust volumetric meshing technique and includes a multithreading capability that reduces the amount of memory used and accelerates time to simulation. This proven technology eliminates the complexity of building and refining a finite element mesh and makes advanced numerical analysis practical for all levels of your organization.

IBIS Package Model Extraction

The ability to generate highly accurate reduced-order SPICE models for use in circuit simulation makes ANSYS Q3D Extractor the ideal software to create IBIS package models. You can study crosstalk, ground bounce, interconnect delays and ringing, which helps you to understand the performance of high-speed electronic designs, such as multilayer printed circuit boards, advanced electronic packages and 3D on-chip passive components. In addition, Q3D Extractor is essential for extracting accurate electrical parasitics of critical interconnect components in the package (bondwires), on the board (critical nets), and for the connection path between the chip, package and board (i.e., connectors, cables, sockets and transmission lines).

Equivalent Circuit Model Creation

You can leverage ANSYS Q3D Extractor to create equivalent circuit models (SPICE subcircuits/ladder-type lumped models). The type of model that Q3D Extractor produces depends on which solver was used. The 2D and 3D field solvers create common formats such as Simplorer SML, HSPICE Tabular W-Element, PSpice, Spectre, IBIS ICM/PKG models and ANSYS CPP models.

Power Converter Design

ANSYS Q3D Extractor is ideal for designing power electronic equipment used in hybrid-electric technologies and power distribution applications to optimize inverter/converter architectures and minimize bus inductance, overvoltage situations and short-circuit currents. The software extracts resistance, partial inductance and capacitance parasitics from high-power bus bars, cables, and high-power inverter/converter modules, then inputs them into ANSYS Twin Builder to study the EMI/EMC performance of a power electronic system. Links to ANSYS Icepak and ANSYS Mechanical enable you to study electrothermal stresses caused by electrical currents.

Touchscreen Design

With Q3D Extractor, you can solve design challenges by analyzing the RLCG matrix data of touchscreen devices. The ability to efficiently solve thin conductive layers, such as ITO, can accelerate solutions up to 22 times over traditional thick metal solution methods.

Multidomain System Modeling

Simplorer is a powerful platform for modeling, simulating and analyzing system-level digital prototypes integrated with ANSYS Maxwell, ANSYS HFSS, ANSYS SIwave, and ANSYS Q3D Extractor. Simplorer enables you to verify and optimize the performance of your software-controlled, multidomain systems. With flexible modeling capabilities and tight integration with ANSYS 3D physics simulation, Simplorer provides broad support for assembling and simulating system-level physical models to help you connect conceptual design, detailed analysis and system verification. Simplorer is ideal for electrified system design, power generation, conversion, storage and distribution applications, EMI/EMC studies and general multidomain system optimization and verification.
