Model Simplification with Dependency Analysis

Trace dependencies of ports, signals, and blocks, slice larger models into simplified standalone models

Dependency analysis is determining the interdependencies of blocks, signals, and model components throughout a model. Use Model Slicer to better understand functional dependencies in large or complex models, where determining dependencies can be a lengthy process. See Workflow for Dependency Analysis.
