Commonly Used Blocks

R2026b

Fundamental blocks for building models, including sources, sinks, math operations, and signal routing

The Commonly Used Blocks library provides quick access to blocks that are frequently needed while building Simulink models. Each block also appears in its primary library category (such as Sources, Math Operations, or Signal Routing) where you can find additional related blocks.

To add blocks from this library to your model, see Add Blocks to Models.
