Product overview


eDSim is a fast and powerful electrical simulation tool for SMPS and analog ICs, integrated in the eDesignSuite tool. It features enhanced accuracy and higher convergence speed for SMPS, enabling a simulation time 10-50x faster than the classical analog SPICE simulators.

The tool is a specific version of the SIMPLIS/SIMetrix simulation environment paired with ST model components, for a full electrical simulation with no limitation of nodes and circuit size.

Design your analog circuit using the eDesignSuite engine, display a preview of it in few seconds with full annotated schematic and BOM, and then run the electrical simulation through eDSim to get fast and accurate simulations and reliable design validation, thus reducing the effort and risks related to hardware prototyping.

With the eDSim tool you can also create your schematic from scratch using ST models or simulate your SMPS and analog ICs from a list of predefined ST application schematics - test benches, that you can partially modify according to your needs.

Software release 2024.03 is now available.
