EDASigrity announced T2B software for transistor to behavioral model conversion that is accurate, fast, globally supported, and practical for on-chip and packaged IO circuits.

Such software is essential for analyzing combined signal and power integrity effects in today’s high-speed designs such as those that include DDR parallel bus interfaces. Models generated by T2B retain transistorlevel accuracy while enabling dramatically improved simulation efficiency.

T2B power-aware behavioral models enable accurate full bus simulations to be completed in hours or minutes, while similar simulations with transistor models often take days. High-speed design teams now have access to a practical design flow that addresses the need for accurate issue identification within short project windows.

T2B software for transistor to behavioral model conversion“It can be difficult to select good driver models to use in high-speed time domain simulations,” said Naoshi Higaki, Deputy General Manager of SoC Design Engineering Division, Fujitsu Semiconductor Limited. “Traditional IBIS models do not provide the accuracy needed for SSO, and transistor models take so long to run that they are not viable either. With T2B we expect to be able to convert transistor level models to IBIS 5.0 power-aware models that retain the accuracy of the original".

Efficient Transient Simulations

The efficient transient simulations enabled by Sigrity's T2B-generated models, can help engineers identify the root cause of signal and power integrity issues and verify fixes, resulting in higher-quality designs with fewer iterations. Broadband chips, packages and board models, can be included in the co-simulations.

In contrast, co-simulation with transistor driver models is impractical for most real-world designs because capacity limitations result in model simplifications that sacrifice accuracy. In addition, T2B automatically generates IBIS 3.2, 4.2, 5.0 and Sigrity accuracy-enhanced models from transistor level driver models, utilizing a familiar and well established flow.

IBIS 5.0 models generated by T2B automation include all BIRD95/BIRD98 power-aware effects. Sigrity’s accuracy-enhanced model provides an even more precise reproduction of the transistor model than IBIS 5.0 models support.

The T2B models can be used for time domain simulations with Sigrity’s SPEED2000 tool, and end-to-end bus simulations with Sigrity’s SystemSI tool. T2B power-aware models also improve accuracy when used with HSPICE and other transient simulators.
