WebThe composite data types are the collection of values. In VHDL, list with same data types is defined using ‘ Array ’ keyword; whereas list with different data types is defined using ‘ Record ’. VHDL examples of array and record are shown in Listing 3.6. Further, random access memory (RAM) is implemented in Section 11.4 using composite type.
