Sigrity_T2B

To keep up with the rapid advances in high-speed interfaces, you need to be able to run accurate, full-bus simulations in hours, instead of days. By converting models from transistor to power-aware IBIS behavioral, Cadence® Sigrity™ Transistor-to-Behavioral Model Conversion (T2B™) can help you meet ever-shorter deadlines by avoiding time-consuming transistor-level simulation and inaccurate non-power-aware IBIS model simulation.
