Choose and Parameterize Blocks

Choose blocks and parameterize them using data sheets, simulation results, SPICE netlists, or FEM models

To model an electrical device, you choose appropriate Simscape™ blocks and parameterize them to meet your design goals.

  1. Select an appropriate block — Simscape Electrical™ libraries often contain several blocks that can model the same type of device but make different modeling assumptions. To increase simulation speed and simplify the design process, choose a block with only as much detail as you need to answer your engineering design questions.

  2. Parameterize the block — Simscape Electrical functions and tools can help you parameterize blocks using manufacturer data or simulation results. You can represent components from specific manufacturers using built-in parts or import parameter values from SPICE netlists or data sheets. You can import parameter values for motors from the designs you develop in finite element (FE) tools and create low-fidelity models of motors, semiconductors, and DC-DC converters by generating reduced-order models (ROMs) of high-fidelity Simscape subsystems.

  3. Validate and tune parameter values — Simscape Electrical tools let you plot block-level characteristics. You can compare these plots to measurements or simulation data and tune parameter values to obtain better agreement. If you do not have measurements or simulation data to parameterize the block, you can instead tune parameter values to satisfy your design requirements and then plot device characteristics to help you select a manufactured part.
