Is there any way to implement conditional compilation in simulink and stateflow. Example: #if (condition) {do something} #else {do something else} #end Iam From Automotive embedded systems background. Conditional compilation is very much required for Embedded systems software developement. I cannot find any block that support use of compiler directives in simulink. Can anyone help?

In Stateflow, you build state machines using a graphical or (new) state transition table interface and conditional logic using flow charts. Find more information about flow charts here: www.mathworks.com/help/stateflow/decision-logic.html
The pattern wizard (user interface window) can be used to quickly build commonly used patterns like the ones you are asking about: http://www.mathworks.com/help/stateflow/ug/creating-flow-graphs-with-the-pattern-wizard.html
hope that helps, Siddharth

Simulink allows Conditional Subsystems which are block groups that are executed if chosen conditions are met. More info in this blog post. I am not sure how to incorporate compiler directives as your question states, but maybe all you want to do is to execute some parts of the model conditionally, which can be done with Conditional Subsystems.

you can use variant subsystem for creating pre processor directive
