You can try the full form of VHDL and gain confidence at least in VHDL full form. Edumantra takes good care of you so buying books for competitive exams is not necessary. Additionally we would like to tell that the full form of VHDL is Vhsic Hardware Description Language.
VHDL— VHSIC Hardware Description Language
The abbreviation, acronym or full form of VHDL is VHSIC Hardware Description Language.
Abbreviation, Acronym or Full Form of VHDL
VHDL is a hardware description language used in electronic design automation to describe digital and mixed-signal systems. VHDL is used as a general-purpose parallel programming language. VHDL was initially developed by the U.S Department of Defence in order to observe the behaviour of ASIC’s that supplier companies were including in equipment.
VHDL is commonly used to write text models that describe a logical circuit. It is strongly typed and is not case-sensitive. It contains an extended set of Boolean operators including NAND and NOR. VHDL allows arrays to be indexed in either ascending or descending direction.
VHDL has file input and output capabilities and can be used as a general-purpose language for text processing. There are a few VHDL compilers which build executable binaries.
VHDL Full-Form refers to VHSIC Hardware Description Language. The VHDL is an IIDL or Hardware Description Language utilized in EDA or Electronic Design Automation for describing mixed-signal and digital systems like integrated circuits and FPGA or Field-Programmable Gate Array. The development of VHDL was the result of the request made by the Defense Department of the US for documenting the ASICs behaviour, which the supplier companies were attaching in their equipment.
The most common use of the VHDL includes the writing of the text models that are used for writing a logic circuit. The processing of such models takes place using a synthesis program, the only condition being that the model must be a portion of the logic design. The logic design is tested using a simulation program, which is a part of the simulation model that represents the circuit that acts as an interface for the design. This simulation models’ collection is referred to as a test bench.
VHDL is also equipped with the input as well as the output capabilities. Hence, it can be utilized as the general-purpose language for processing the text. However, a simulation test bench usually uses files for data verification. Certain VHDL compilers have the ability to build binaries that can be executed. In such cases, VHDL can be used for writing a test bench that can verify the design’s functionality by utilizing files present in the host computer for defining the stimuli.
A VHDL IDE can be used for designing hardware that can produce the RTL or register-transfer level schematic of any circuit. The verification of the resultant schematic can be done by utilizing simulation software. This software will show the circuit’s input and outputs after the generation of the test bench. The correct definitions of the inputs are necessary for generating appropriate test benches for VHDL code or a circuit. Finally, the VHDL can be also be utilized as a PPL or parallel programming language.
Advantages of VHDL –
- VHDL allows the behaviour of the required system to be described (modelled) and verified (simulated) before synthesis tools to translate the design into real hardware (gates and wires).
- VHDL allows the description of a concurrent system.
- VHDL is a dataflow language, unlike procedural computing languages such as BASIC, C, and assembly code, which run sequentially, processing one instruction at a time.
- A VHDL project is multipurpose. Being created once, a calculation block can be used in many other projects.
- A VHDL project is portable. Being created for one element base, a computing device project can be ported on another element base.
