Syntax for declaration of a DUT:
TYPE <identifier> : <DUT components declaration>
END_TYPE
The DUT components declaration depends on the type of DUT, e.g. a structure or an
enumeration.
Example:
See in the following two DUTS, defining structures struct1 and struct2; struct2 extends
struct1, which means that you can use "
struct2.a
" in your implementation to access
variable a.
TYPE struct1 :
STRUCT
a:INT;
b:BOOL;
END_STRUCT
END_TYPE
TYPE struct2 EXTENDS struct1 :
STRUCT
c:DWORD;
d:STRING;
END_STRUCT
END_TYPE
