In computer engineering, a hardware description language (HDL) is a specialized computer language used to describe the structure and behavior of electronic circuits, usually to design application-specific integrated circuits (ASICs) and to program field-programmable gate arrays (FPGAs).
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.
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.
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 ...
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

This description, often called a hardware design model, allows hardware designers to understand how their components fit into a system architecture and provides to software component designers important information needed for software development and integration. Clear definition of a hardware architecture allows the various traditional ...
SystemC has semantic similarities to VHDL and Verilog, but may be said to have a syntactical overhead compared to these when used as a hardware description language. On the other hand, it offers a greater range of expression, similar to object-oriented design partitioning and template classes. Although strictly a C++ class library, SystemC is ...
