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

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 www.st.com/twistersim-forum to help users.

The tool is free of charge and can be downloaded from our website at www.st.com/twistersim

Quickly and accurately identify inter-domain leakage issues in IC designs

Sponsored by Siemens Digital Industries Software

Power domain leakage is a major IC reliability issue, often missed by traditional tools. This white paper describes challenges of identifying leakage, types of false results, and presents Siemens EDA’s Insight Analyzer. The tool proactively finds true leakage paths, filters out false positives, and helps circuit designers quickly fix risks—enabling more robust, reliable chip designs. With detailed, context-aware analysis, designers save time and improve silicon quality.
