Ansys VeloceRF
Inductor and Transformer Design Tools

Ansys VeloceRF is an inductive device synthesis and modeling tool that supports advanced nodes as low as 3nm and integrates with leading EDA platforms.

INDUCTORS AND TRANSMISSIONS LINES

Synthesize and Model Spiral Devices and T-lines to 3nm

Ansys VeloceRF shortens the design cycle by greatly reducing the time it takes to synthesize and model complex spiral devices and T-lines. It takes only a few seconds to compile an inductor or transformer geometry, and just a couple of minutes to model and analyze it. It integrates with leading EDA platforms, instantiating ready-to-tape-out layouts.

Ansys VeloceRF shortens the design cycle by greatly reducing the time it takes to synthesize and model complex spiral devices and T-lines.

Inductor size as well as inductor-to-inductor crosstalk can impact the die size. Ansys VeloceRF helps you design smaller devices through the use of optimization criteria and geometry constraints. In addition, it calculates coupling among any number of inductors to better optimize silicon real estate and to optimize inductors in circuit context. Ansys VeloceRF’s parametric sweep support delivers an optimal performance solution in circuit context. The foundry-verified accuracy mitigates risk in your design with silicon-proven models that help eliminate crosstalk failures.

Ansys VeloceRF currently supports over 200 unique foundry processes and works with any process down to 3nm including CMOS, BiCMOS, GaAs, SOS and SOI from all semiconductor foundries - TSMC, UMC, Global Foundries, TowerJazz and Samsung, among others. The tool integrates with leading EDA design platforms and with any LVS tool.

Applications

Synthesize and model spiral devices and T-lines for mm-wave design down to 3nm

Ansys VeloceRF synthesizes and analyzes mm-wave spiral devices and T-lines in just a few minutes. It generates DRC/DFM clean devices - including fill - down to 3nm. The devices are modeled by passive, causal S-parameters and highly compact RLCk netlist models and can be delivered as PCells/PyCells for maximum geometric flexibility. In-context optimization allows significant die size reductions through tight floor plan packing of multiple devices and lines and the reduction or elimination of guard rings. It supports high frequency with a pre-defined library of device building blocks and supports coupling among any number of inductive devices.

Key Features

VeloceRF delivers comprehensive synthesis, modeling, analysis and optimization of inductive devices on silicon.

  • Silicon verified
  • Optimize floorplan packing
  • Reduce device size
  • Library of pre-defined shapes
  • Optimize performance with parametric sweeps
  • Supported on over 200 silicon technologies

Single-spiral inductors: Differential, single-ended, square and octagonal, with or without center taps.

Multispiral inductors: Transformers, baluns, T-coils and series differential.

T-lines: Shielded, double-shielded, strip lines, couplers, combiners and other types that are ready to tape out.

Ansys VeloceRF calculates coupling among any number of inductors to better optimize silicon real estate. With VeloceRF, you can tighten or eliminate guard rings and also optimize the silicon floorplan.

Ansys VeloceRF provides parametric sweep support of inductor parameters to deliver an optimal solution in circuit context. It allows unique coupling analysis among inductors to ensure crosstalk-related failures are eliminated.

Ansys VeloceRF provides proven silicon accuracy for designs at mm-wave frequencies. A wide array of T-line structures support a LEGO®-like approach to design, including: microstrip lines, coplanar waveguides (shielded and double shielded), striplines, 45- and 90-degree bends, T-junctions, stubs, branchline coupler, Wilkinson dividers, etc.

Ansys VeloceRF currently supports over 200 unique foundry technologies and works with any process (CMOS, BiCMOS, GaAs, SOS, SOI) from semiconductor foundries, including TSMC, UMC, Global Foundries, TowerJazz, Samsung, and others. VeloceRF supports all process nodes down to 3nm. It integrates with leading EDA platforms and VeloceRF models can be combined with parasitic extracted netlists.

Ansys VeloceRF computes layout-dependent effects (LDE) before the full 3D-meshing algorithm segments the conductors’ volume into small cells. A 3D substrate model allows for very fast and accurate extraction of the distributed RC substrate network. Extracted models are extremely accurate, capturing all electromagnetic phenomena, including current distributions, skin and proximity effects.
