Free Software Tool from STMicroelectronics Includes Accurate Dynamic Simulation for VIPower Devices

Geneva, Switzerland – WEBWIRE

Geneva, March 19, 2015 –  TwisterSIM is a unique free software suite that includes a Smart Interactive Selector and a Dynamic Electro-Thermal Simulator for Automotive Low/High-side driver/switches and H-bridges for motor control built using ST’s proprietary VIPower™ technology. The tool allows complex evaluations with accurate dynamic simulations of load-compatibility, wiring-harness optimization, fault condition impact analysis, diagnostic behavior analysis and Dynamic Thermal performance in just a few clicks.
TwisterSIM considerably reduces the cost and time needed to select and validate a product for a specific application layout by performing a thermal-electrical dynamic simulation.
Key features include:
·         Built in library of accurate VIPower-product models based on a proprietary methodology and validation that allows a realistic reproduction of “in application” behavior;
·         Step-by-step guided selection of the optimal device for a specific application;
·         Built-in load library for automotive lamps and generic loads;
·         Simulation results, including junction thermal profiles, load current, and diagnostic behavior, are shown on dedicated scope views and can be exported in multiple commonly-used formats;
·         User selectable wide range of environmental conditions and real device parameters;
·         Direct links to the product web page to view related datasheet and product collaterals;
·         On-line forum is available at to help users.
The tool is free of charge and can be downloaded from our website at
