Sigrity T2B

Sigrity Transistor-to-Behavioral (T2B) model conversion enables accurate system-level simulation and is now essential due to the rapid advance of high-speed interface technologies. Time-consuming transistor-level simulation and inaccurate traditional IBIS model simulation fail to measure up in simulations such as SSO studies where power delivery effects play a crucial role.

Sigrity T2B

The T2B solution converts models from transistor to behavioral, enabling accurate and efficient full bus simulations in hours instead of days. It outputs models in IBIS 3.2, 4.2, and 5.0 formats as well as in an accuracy-enhanced Sigrity behavioral model format. Power-aware behavioral driver models generated by Sigrity T2B maximize accuracy and support highly efficient simulations using Sigrity SPEED2000 and SystemSI technology, or other compatible simulators such as HSPICE.
Sigrity T2B
