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.
There are now two industry standard hardware description languages, VHDL and Verilog. It is important that a designer knows both of them although we are using only VHDL in class. Verilog is easier to understand and use. For several years it has been the language of choice for industrial applications that required both simulation and synthesis.
VHDL is one of the type of hardware description language which describes the behavior of an integrated circuit or system which is used to implement physical circuit or system. VHDL is an abbreviation for VHSIC which stands for Very High Speed Integrated Circuit Hardware Description Language.
VHDL is one of the two languages used by education and business to design FPGAs and ASICs. You might first benefit from an introduction to FPGAs and ASICs if you are unfamiliar with these fascinating pieces of circuitry.
VHDL in-cludes facilities for describing logical structure and function of digital systems at a number of levels of abstraction, from system level down to the gate level. It is intend-ed, among other things, as a modeling language for specification and simulation.
Abstract: VHSIC Hardware Description Language (VHDL) is defined. VHDL is a formal notation intended for use in all phases of the creation of electronic systems.
VHDL stands for very high-speed integrated circuit hardware description language. It is a programming language used to model a digital system by dataflow, behavioral and structural style of modeling.
