What is the full form of VHDL
VHDL: VHSIC (Very High Speed Integrated Circuit) Hardware Description Language
VHDL is a hardware description language that is used to model the physical hardware used in digital systems like in logic circuits to tell their structure, timing and behavior. It should not be confuse with a programming language as it is not a programming language. There are some predefined data types in VHDL, apart from these a user can also define its own data type.
It was developed by the U.S. Department of Defense in 1981.
