Simulink Truthtable block with Action language as C

Is it possible to set Action language to C in Simulink Truthtable block? For truth tables used in Stateflow model, there is an option to select Action Language. But this option is not available for Simulink Truthtable block.

Is it a limitation or is there any possibility to set it to C language?

Hey Arunkumar,

As far as I understand, unlike Stateflow charts, where you can set the action language to C or MATLAB, the Truth Table block in Simulink does not provide an option to choose the action language as C directly. The primary reason is that the Truth Table block is intended to be a high-level abstraction for decision logic, which is typically implemented using MATLAB for ease of use and integration within the Simulink environment.

If you need to use C as the action language for decision logic, I would suggest you the following:

• Use Stateflow charts instead of a Truth Table block, and set the action language to C as you have already mentioned.
• Use a custom S-Function block with the logic written in C to be used in Simulink. This would give you flexibility to write C code but requires some more effort to implement.
• You can also use the Legacy code tool to integrate existing C functions in Simulink.

I hope this helps!
