Sigrity Broadband SPICE technology performs S-parameter checking and model tuning, accurately converting network parameters to SPICE-equivalent circuits. It provides 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.
Broadband SPICE accepts network parameters such as the scattering, impedance, or admittance (S, Z, or Y) parameters of N-port passive networks from Touchstone files and from the more compact Cadence® Broadband Network Parameter (BNP) format. The compact black-box models created by Broadband SPICE offer excellent convergence.
Features
- Creates SPICE-equivalent circuits from network parameters
- Bridges frequency and time domains
- 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
Benefits
- Easy touch-button model creation for use with HSPICE and general SPICE simulators
- Simplified use of S-parameter data reduces simulation issues and accelerates transient simulation runtimes
- Accurate and compact model creation improves SPICE simulation convergence and speed
- 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
- Supports both Touchstone files and the more compact Cadence BNP format
