As such an integer type and two subtypes have been defined in VHDL. For example, if integer has values from 0-7 only, then we can define 'unsigned' data type of width 3 as shown in Listing 3.7. 3.3.3. 'textio' and 'std_logic_textio' 29 Jan 2018 VHDL doesn't specify the exact number of bits, but any VHDL implementation should support at least a 32-bit realization for the integer type.
However, we can limit the range of the integer to save resources in our FPGA when writing VHDL code. For example, we may require a signal which counts from 0 to 150.

We can use types which interpret data purely as logical values, for example.
