Hdl Behavioral Description
The electrical behavior described by this code can be visually represented as follows.
Hdl behavioral description. 9 out1 a and b. In vhdl the architecture includes the keyword process. Hardware description language hdl is a specialized computer language used to program electronic and digital logic circuits. The structure operation and design of the circuits are programmable using hdl.
Hdl includes a textual description consisting of operators expressions statements inputs and outputs. A behavioral description is based on the manner in which outputs behave with the inputs. Verilog hdl 3 edited by chu yu verilog hdl hdl hardware description language a programming language that can describe the functionality and timing of the hardware why use an hdl. In computer engineering a hardware description language hdl is a specialized computer language used to describe the structure and behavior of electronic circuits and most commonly digital logic circuits.
These styles are common to vhdl and verilog hdl. It is becoming very difficult to design directly on hardware it is easier and cheaper to different design options reduce time and cost.
