What you'll see
Your model opens at its top system, drawn as Simulink draws it, with every subsystem on a page of its own.

About SLX
Simulink, MathWorks' block diagram tool on top of MATLAB, models systems that change over time: control loops, motors, circuits, vehicles and the code that runs them. Carmakers, aircraft makers and universities pass models around as .slx files, and only Simulink opens them.
Since 2012 a model is an .slx, a ZIP in Office's Open Packaging with its block diagram in XML: each system's blocks with their places and parameters, the lines between their ports with their branches, its notes, and each subsystem's own system, beside a picture of the top one. Older models are .mdl files, the same diagram as text.
Filepeek reads the model in your browser, with nothing simulated and nothing it names fetched. Each system is drawn as Simulink draws it: its blocks in their shapes and icons, like Gain, Sum, Integrator, Transfer Fcn and Scope, their ports, the signal lines with their branches and names, and its notes, each subsystem on a page of its own. A block from a library or a model it refers to shows by its name. Search finds a block, and Export saves a page as SVG or PNG, or every page as PDF.

Opens in every browser
Filepeek opens Simulink models in Chrome, Edge, Firefox and Safari, with no MATLAB to install. On their own, browsers download them, and Simulink needs MATLAB and a licence of its own.

Questions
How do I open an .slx file without MATLAB?
Drop it on this page or choose Peek an SLX. Its top system opens as Simulink draws it, and each subsystem is a page of its own.
Can I run the simulation?
No. Filepeek only draws the model, and nothing in it runs. Simulating it takes Simulink.
Why does a block show only its name?
It comes from a library or a model it refers to, which the model only names, and Filepeek fetches nothing, so it draws the block with its name and ports. A Stateflow chart shows as its block, without the states inside it.
Does it open .mdl models?
Yes. Simulink's models from before 2012, and those saved as .mdl since, open as their block diagrams the same way.
