Sigrity Broadband SPICE

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
