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
