Integer data type It can hold an integer number ranging from - (2 31 – 1) to + (2 31 – 1). Interestingly two subtypes of integers are also defined in the standard library of VHDL. Now, what are subtypes you ask, in short, a subtype is a datatype which has constrained values of its base type. In VHDL terms, you will get a range error when you try and simulate it and your simulation will fail when counter is zero.

If n is not specified for the INTEGER, the default is 8-bytes. The optional IntType may specify either the BIG_ENDIAN (Sun/UNIX-type, valid only inside a RECORD structure) or LITTLE_ENDIAN (Intel-type) style of integers.

CONV_INTEGER--Converts a parameter of type INTEGER, UNSIGNED, SIGNED, or STD_ULOGIC to an INTEGER value. The size of operands in CONV_INTEGER functions are limited to the range -2147483647 to 2147483647, that is, to a 31-bit UNSIGNED value or a 32-bit SIGNED value.

Attributes also allow you to assign additional information (such a It is like if ISim don't support integer ranges and takes the variable like a 32-bit Integer. And I just want to limit my variable to 15 bits. After synthesis my variable has 15 bits if I write range attribute.
