To define an array of strings, you have to allocate space at compile-time for the highest number of strings you want to store. And even worse, you must decide on the strings’ max length and pad every occurrence to that number of characters. As with most programming lanaguges, the integer type in VHDL is 32-bits wide by default. 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. Therefore, we can implement this as an 8 bit integer within our FPGA.

VHDL is case insensitive language i.e. upper and lower case letters have same meanings. Further, 1-bit numbers are written in single quotation mark and numbers with more than 1-bit are written in double quotation mark, e.g. ‘0’ and ‘‘01’’ are the valid notations.

This would not be allowed if each array length was declared as separate data type. VHDL does not put any restrictions on the index set of arrays, as long it is a discrete range of values. It is even legal to use enumeration types, as shown in the code example, although this version is not generally synthesizable.

9/17/09 5:57 PM. Hi, I need to get the length of a record in order to set an integer constant, like this: type T_MyRecord is record. element_1 : unsigned (3 downto 0); element_2 : unsigned (2 downto 0); Arrays are used in VHDL to create a group of elements of one data type. Arrays can only be used after you have created a special data type for that particular array. Below are some rules about arrays.
