View Data During Simulation

View data during simulation using Scope blocks, the Record block, or the Simulation Data Inspector

Scope blocks and scope viewers offer a quick way to visualize simulation data over time. If you are prototyping a model, connect signals to a Scope block, simulate the model, and then view the results in a scope window. Use the results to validate your design. If you need to debug your model, use oscilloscope-like tools in the Scope, such as triggers and cursor measurements, to locate the problem. To learn more, see Prototype and Debug Models with Scopes.

Blocks

Scope	Display signals generated during simulation
Floating Scope and Scope Viewer	Display signals generated during simulation without signal lines
Record	Log data to the workspace, to a file, or both (Since R2021a)

Objects

TimeScopeConfiguration Control Scope block appearance and behavior

Tools

Simulation Data Inspector

Inspect and compare data and simulation results to validate and iterate model designs
