A hardware description language looks much like a programming language such as C or ALGOL; it is a textual description consisting of expressions, statements and control structures. One important difference between most programming languages and HDLs is that HDLs explicitly include the notion of time.
VHDL source for a signed adder. VHDL (VHSIC Hardware Description Language) is a hardware description language that can model the behavior and structure of digital systems at multiple levels of abstraction, ranging from the system level down to that of logic gates, for design entry, documentation, and verification purposes.
Software can, through the interpretation of a device description (DD), configure and control many different devices. The creation of a description with the DDL is less effort than writing an entire software tool. The HART Communication Foundation, PROFIBUS and Fieldbus Foundation have merged their individual dialects of the DDL.
Hardware description language – used to model integrated circuits; Page description language – describes the appearance of a printed page in a higher level than an actual output bitmap; Simulation language – a language used to describe simulations; Specification language – a language used to describe what a system should do

The concept of TLM first appears in system level language and modeling domain. [3] Transaction-level models are used for high-level synthesis of register-transfer level (RTL) models for a lower-level modelling and implementation of system components. RTL is usually represented by a hardware description language source code (e.g. VHDL, SystemC ...
An optical communication system is any form of communications system that uses light as the transmission medium. Equipment consists of a transmitter, which encodes a message into an optical signal, a communication channel, which carries the signal to its destination, and a receiver, which reproduces the message from the received optical signal.
Verilog, standardized as IEEE 1364, is a hardware description language (HDL) used to model electronic systems.It is most commonly used in the design and verification of digital circuits, with the highest level of abstraction being at the register-transfer level.
