Accurately convert network parameters to SPICE-compatible circuits
Key Benefits
• Fast, easy model creation from N-port passive parameters for HSPICE
and SPICE simulators
• Reduces simulation issues and accelerates transient simulation runtimes
• Accepts Touchstone or Sigrity BNP files
To reduce simulation issues and accelerate your transient simulation runtimes,
Cadence® Sigrity™ Broadband SPICE™ technology accurately and quickly converts
N-port passive-network parameters such as scattering, impedance, or admittance
(S, Z, or Y) into SPICE-equivalent circuits that can be used in time-domain simulations.
You can feed it data from Touchstone files and also from the more-compact Cadence
Broadband Network Parameter (BNP) format.
Sigrity Broadband SPICE technology gives you a passive compact circuit model while
maintaining accuracy for efficient transient simulations in HSPICE, or other
SPICE-compatible circuit simulators, including the Sigrity SPEED2000™ time-domain
simulator. The resulting compact black-box models created by Broadband SPICE give
you excellent convergence.
Features
• Generates models for DC through broadband frequencies
• Extracts network models with multiple resonance points
• Models a broad range of structures including IC packages, RF components,
PCBs, cables, and connectors
• Assesses real-world situations such as parallel traces traversing a split plane,
spiral inductors, and return path discontinuities
• Generates a very high order, but numerically stable, model for complex network
responses
• Enables analysis of PI/SI issues such as what-if optimization of power delivery
system performance and simultaneous switching output simulation
• Rigorous passivity enforcement assured by automated techniques along with
interactive user review and control
• Automatic determination of topology and circuit order based on network parameter
curve complexity
• Flexible to support flows where the target simulator may vary and where models
are provided to others
