What Is Verilog?

Verilog is defined as a hardware description language which is used in model electronic systems.  Verilog is standard as IEEE 1364 (Institute of Electrical and Electronics Engineers) for using it in designing and verifying   the technology in register-transfer level of abstraction.   It is commonly used for verifying digital circuits (Schkufza, Wei and Rossbach 2019).  Apart from   digital circuits, it is also used for mixed-signal circuits and analogue circuits verifications.  However, in 2009, this hardware description language officially merged into the System-Verilog standard (Chen,  Raginsky and Rosenbaum 2017). 

Verilog is initially developed from a combination of two words such as “verification" and "logic”. In 1983 and 1984, Verilog was created by four scientists such as Phil Moorby, Douglas Warmke,  Prabhu Goel and Chi-Lai Huang.  All of these four scientists Profound experience in working with hardware description language which led to the creation. Initially it was developed for describing and allowing simulation as well as automated synthesis of subsets of the language for physically realizable structures like gates (Lööw 2021). However, considering the layman's point of view, Verilog is one of the widely used hardware description languages similar to software program languages (Vivekananda and Enoiu, E., 2020).  This language contains two assignment help online operators such as blocking and non-blocking which enable designers to develop large circuits concisely and compactly.  Verilog development has altered the landscape   of circuit design because it shows tremendous productivity improvement for circuit designers who have skills for using graphical schematic capture software and written software programs (Rout and Mahapatro 2020). This program supports them to document as well as simulate electronic circuits in software development.

What Does VHDL Mean?

VHDL is usually requires in the engineering as example civil engineering in order to write text models that describe a logic circuit. In other words, VHDL is Very High-Speed Integrated Circuit (VHSIC) Hardware Description Language which together creates the abbreviation of (VHDL) (Ahmed, Ghoneima and Dessouky 2018). It is well known language which is used for circuit designers for identifying as well as describing the behaviour of electronic circuits, the most commonly digital circuits (Vivekananda and Enoiu, E., 2020).

What Is VHDL and Give Its Features?

VHDL Is considered as the hardware language that models the behaviour of any digital system at various level of abstraction.  abstraction can range from logic Gate verification purpose and enter documentation. Unlike Verilog, it is standard as IEEE 1076 (Institute of Electrical and Electronics Engineers) for Modelling analogue as well as mixed signal system (Ahmed, Ghoneima and Dessouky 2018). Initially the name was created after the name of a US based program such as United States Department of Defence program (Ahmed, Ghoneima and Dessouky 2018). It was originally developed for documenting behaviour of Application specific integrated survey which was provided by supplier company within any equipment (Vivekananda and Enoiu 2020).  However, in the early 1980s, it was officially launched for use in the design of integrated circuits in electronics engineering  

This hardware description system usually has various features which can be used for the design of integrated circuits.  For example, unlike other   hardware language systems it is one of the widely used standard languages that can describe digital systems (Da Costa and Santin 2017). Hence, it offers added benefit to the circuit designer while working with digital systems. Similarly, it exhibits con currency and is able to support sequential statements. Unlike many hardware languages, it can support the simulation and test as it has strongly typed language (Trost and Žemva 2019). Hence, it provides added benefit for the system designer since it allows the behaviour of the required system to be modelled as well as simulated prior to synthesis tools to translate the design into real hardware such as gates and wires.  The electric automation supports obtaining design within a short period of time (Ahmed, Ghoneima and Dessouky 2018). 

What Is the Difference Between Verilog and VHDL?

 The are various differences in between Verilog and VHDL which were implemented in literature. For example, Verilog is considered as hardware description language for the circuit designer as it is used for modelling electronic systems. However, VHDL is also a hardware description language but is specifically used for   describing digital and mixed-signal systems.  Compared to VHDL, Verilog is considered as the new hardware language which was developed in 1984 while VHDL was developed in 1980.  There is also language difference between Verilog and VHDL.  While Verilog uses C languages, VHDL uses Ada and Pascal languages (LaMeres  2017).  Hence, Verilog is used in many electronic designs as   it is using many data types that are predefined.However, Verilog is very much Case sensitive unlike VHDL which is not case sensitive (LaMeres  2017).  This program is easy to learn and people with background knowledge of C experience no difficulty in learning this language. However, VHDL require excessive support and learning process in order to improve circuit designs.

What Are the Main Differences Between Task and Function in Verilog?

From layman’s perception, function is defined as the action while task is a piece of work that must be done as a part of the responsibility (Vivekananda and Enoiu, E., 2020). In Verilog, the main difference between function and task is that task usually has a more general form which requires calculation of multiple results values. Hence, after calculation, these results are integrated in output and input type arguments. In Verilog, this task section contains Verilog code which supports digital designers to write easily readable and reusable codes so that next designers can review the task before identifying behaviours of the circuit (LaMeres 2017).  However, on the other hand, the function of Verilog is to work on   processing on the input and return a single value (Ahmed, Ghoneima and Dessouky 2018). Functions can use and modify global variables, when no local variables are used. Hence, it provides added benefit for the system designer since it allows the behaviour of the required system to be modelled as well as simulated prior to synthesis tools to translate the design into real hardware such as gates and wires (Ahmed, Ghoneima and Dessouky 2018).
