SANTA CLARA, Calif. — May 21, 2002 — SIGRITY, INC. today announced the release of a new software tool, Broadband SPICE™, for generating accurate SPICE circuits over broadband frequencies for networks of complex frequency domain responses.

Broadband SPICE™ extracts highly accurate SPICE equivalent circuits from network parameters over broadband frequencies. The network parameters can be scattering, impedance or admittance (S, Z or Y) parameters of an N-port network in Touchstone™ file format. The N-port network can be as simple as a two-terminal (1-port) component or a multi-port complex system. The network parameters can be obtained from actual measurements or from full-wave, broadband electromagnetic field solvers.

HSPICE™, PSPICE™, or other SPICE compatible circuit simulators, including SIGRITY’s own time-domain simulator SPEED2000™, can then use the extracted SPICE circuits for DC, AC and transient analysis. Broadband SPICE™ can be used as a stand-alone tool for the conversion of network parameters to SPICE circuits.

Capabilities of existing tools on the market for similar functions have various limitations that can be characterized as follows:

SIGRITY’s breakthrough technologies implemented in Broadband SPICE™ yield the following superior properties:

PowerSI, SIGRITY’s full-wave power and signal integrity tool optimized for frequency-domain analysis, and Broadband SPICE™ can closely work together. After completing the frequency-domain analysis in PowerSI, the computed results can be exported in Touchstone™ format, which can then be loaded into Broadband SPICE™ and converted to SPICE circuits. The SPICE circuits generated by Broadband SPICE™ can also be used in SPEED2000™ for time-domain simulations.

Pricing and Availability
Broadband SPICE™ is available now! North America customers may request an evaluation license by contacting SIGRITY’s sales office (408-260-9344) or please send an Email: Customers outside of North America should contact their local sales representatives.

Perpetual license pricing starts at $10,000 (plus $1,500 for annual maintenance). A one-year license is also available. A special promotion for early adopters will be offered on orders received by July 31, 2002. Contact SIGRITY or your sales representative for details.
