en.wikipedia.org/wiki/VHDL

VHDL (VHSIC Hardware Description Language) is a hardware description language used in electronic design automation to describe digital and mixed- signal systems such as field-programmable gate arrays and integrated circuits. VHDL can also be used as a general purpose parallel programming language.

HDL (Hardware Description Language) based design has established itself as the modern approach to design of digital systems, with VHDL (VHSIC Hardware Description Language) and Verilog HDL being the two dominant HDLs. Numerous universities thus introduce their students to VHDL (or Verilog). The problem is ...

VHDL is a horrible acronym. It stands for VHSIC Hardware Description Language . An acronym inside an acronym, awesome! VHSIC stands for Very High Speed Integrated Circuit. Therefore, VHDL expanded is Very High Speed Integrated Circuit Hardware Description Language. PHEW that's a mouthful. VHDL is one of the ...

The development of VHDL was initiated in 1981 by the United States Department of Defence to address the hardware life cycle crisis. The cost of reprocuring electronic hardware as technologies became obsolete was reaching crisis point, because the function of the parts was not adequately documented, and the various ...

What is VHDL? VHDL is the VHSIC Hardware Description Language. VHSIC is an abbreviation for Very High Speed Integrated Circuit. It can describe the behaviour and structure of electronic systems, but is particularly suited as a language to describe the structure and behaviour of digital electronic hardware designs, such ...

VHDL Introduction. A language for describing the structural, physical and behavioral characteristics of digital systems. Execution of a VHDL program results in a simulation of the digital system. Allows us to validate the design prior to fabrication. The definition of the VHDL language provides a range of features that support ...

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. This language was first introduced in 1981 for the department of Defense (DoD) under the VHSIC program.

The entity is called BUZZER and has three input ports, DOOR, IGNITION and SBELT and one output port, WARNING. Notice the use and placement of semicolons! The name BUZZER is an identifier. Inputs are denoted by the keyword in, and outputs by the keyword out. Since VHDL is a strongly typed language, each port ...
