ss2sf - Subsystem-to-S Function

Convert a subsystem to an s-function via the MATLAB command line.

Description

Typically, you have to right-click on a subsystem, choose Real Time Workshop -> Generate S-Function in order to replace a standard Simulink subsystem with an S-function.

With ss2sf, you can provide a cell array of subsystem paths and the function will replace the specified subsystems with their s-function equivalents.

• Required Products: Real-Time Workshop; Simulink
• MATLAB release: MATLAB 7 (R14)

This works fine when you don't use busses. When a bus is used you can get error messages like this:
'model/subsystem' must be connected to a Bus Creator, Bus Selector or a block that outputs a bus using a bus object. It can also be connected to bus capable blocks that meet the conditions for supporting buses provided the bus entering the block has been created by using a bus creator.

The internal S-Function Generator works somehow different. It seems to split the bus signals into single signals. An information how that works would be appreciated.
