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.
C to HDL tools convert C language or C-like computer code into a hardware description language (HDL) such as VHDL or Verilog.The converted code can then be synthesized and translated into a hardware device such as a field-programmable gate array.
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.
The code is analyzed, architecturally constrained, and scheduled to transcompile from a transaction-level model (TLM) into a register-transfer level (RTL) design in a hardware description language (HDL), which is in turn commonly synthesized to the gate level by the use of a logic synthesis tool.
HDL simulators are software packages that simulate expressions written in one of the hardware description languages, such as VHDL, Verilog, SystemVerilog. This page is intended to list current and historical HDL simulators, accelerators, emulators, etc.
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.

Chisel (an acronym for Constructing Hardware in a Scala Embedded Language [1]) is an open-source hardware description language (HDL) used to describe digital electronics and circuits at the register-transfer level. [2] [3] Chisel is based on Scala as a domain-specific language (DSL).
