Thanks for reply Enrico.
I am using WESTforOPTIMIZATION 2016 for 64bit.
I just open a blank project and start creating my layout, entering inputs, outputs and others.. I save it in an individual folder in my directory.
I haven't editted any standart model.
On those lines I mentioned as [b]#ifndef'[/b] and [b]'#define'[/b], the name of my project is written as usual.
For istance the line is like this; [b]#ifndef'[/b] __PROJECTNAME_MSL___ ( I observe it by using Notepad++)
Even if I try to change something in syntax, as soon as I try to re-run my simulation the software automtically changes it to its old line.
