PAT Technology

Beyond System Simulation —
Down to Every Switching Transient

DSIM uses innovative Piecewise Analytical Transient (PAT) models that decouple the key switching characteristics of semiconductor devices from first principles.

Nanosecond Resolution, System-Level Simulation

PAT models efficiently solve turn-on and turn-off processes for IGBTs, SiC MOSFETs, and more — extending time resolution down to nanoseconds even in large system simulations.

Multi-Timescale Unified Modeling

Device-level PAT models build into system-level models with conditional timescale decoupling, significantly reducing numerical stiffness and ensuring fast, convergent simulation.

100+ Built-in Device Models

Covering hundreds of mainstream IGBT and SiC MOSFET devices, ready to use out of the box.

Direct Thermal-Electric Coupling

Switching transient results directly feed loss calculations and thermal dissipation simulation — evaluate junction temperatures and system thermal topology in real time.
