Create Signal Data for Simulation

Create input data to load into a model as simulation input

Create input data to load into a model as simulation input. You can create signal data in the MATLAB^® workspace or use the Signal Editor block. Optionally, create and import custom file types for signals.

Blocks

Signal Editor

Display, create, edit, and switch interchangeable scenarios

Live Editor Tasks

Create Signal

Create signal in Live Editor (Since R2022b)

Tools

Signal Editor

Create and edit input signals

Functions

`signalBuilderToSignalEditor`	Import signal data and properties from Signal Builder block to Signal Editor block
`signalbuilder`	(Not recommended) Create and access Signal Builder blocks
`Simulink.io.getFileTypeDiagnostics`	Return structure with `NamespaceErrors` field for `Simulink.io.FileType` objects (Since R2021a)
