How does vhdl relate to the altera quartus?
Quartus is an EDA tool provided by Altera. The very purpose of EDA tools is to simulate hardware description languages. VHDL is a hardware description language. Hence, Quartus is used to simulate VHDL programs.
What is the difference between fpga implementation and verilog implementation?
Verilog HDL / VHDL is a hardware description language used to implement a hardware on a computer virtually. It means that we can append all the attributes of a hardware to a computer program and verify as to how it works. But there may be differences in its behavior when it is actually implemented physically. For example, there may be an unexpected time delay. So, it is required to verify the design physically. Hence, we dump this Verilog / VHDL code into an FPGA / CPLD and verify the design physically. In other words, Verilog HDL / VHDL program is used to verify the design on a computer where as FPGA / CPLD implementation is used to verify the design on an IC.
How can you write a VHDL code for full adder using two half adders?
Since a fulladder can be obtained by using 2 halfadders & 1 OR gate.....so we have to call an halfadder program as well as an OR program......this can be implemented easily with the help of structural model rather than dataflow and behavoioural model
What is VHDL program for 2 to 1 multiplexer?
library IEEE;use IEEE.STD_LOGIC_1164.ALL;use IEEE.STD_LOGIC_ARITH.ALL;use IEEE.STD_LOGIC_UNSIGNED.ALL;entity mux2x1 isPort ( i : in STD_LOGIC_VECTOR (1 downto 0);s : in STD_LOGIC;y : out STD_LOGIC);end mux2x1;architecture df of mux2x1 isbeginwith s selecty
What is VHDL program for full adder in data flow model?
library IEEE; use IEEE.STD_LOGIC_1164.ALL; use IEEE.STD_LOGIC_ARITH.ALL; use IEEE.STD_LOGIC_UNSIGNED.ALL; entity fadf is Port ( ain : in STD_LOGIC; bin : in STD_LOGIC; cin : in STD_LOGIC; sum : out STD_LOGIC; cout : out STD_LOGIC); end fadf; architecture df of fadf is begin sum<= ain xor bin xor cin; cout<= (ain and bin) or ( bin and cin) or (ain and cin); end df;
Diploma person can do vhdl?
Yes. A little knowledge of programming is needed to learn VHDL. Knowledge in digital electronics is a must. One should be in a position to understand the working of various combinational and sequential circuits to expertise in VHDL.
What is VHDL calculators?
A virtual calculator can be implemented using VHDL. We call it VHDL calculator.
Why vERILOG is better than vHDL?
VHDL is a system level programming language and Verilog is a circuit level programming language. VHDL can be viewed as a language written in programmer's point of view. In that manner it is better than VHDL. For example, to write a code for a simple combinational circuit, we need to define from the circuit level in Verilog i. e. FET level. But in VHDL, we can directly take several smaller components and combine them to trealize the circuit. That means, one need not have a knowledge of analog circuits to design something in VHDL. He only needs to know the behavior of the desired design.
How do you build 8085 using vhdl?
VHDL is a hardware description language. It describes the functionality of a hardware as a program. If we know the architecture of 8085, the same can be implemented or coded using VHDL.
Why use process statement in vhdl?
Almost all programming languages are sequential in nature. But VHDL is a concurrent language. In an architecture for an entity, all statements are concurrent. So where do sequential statements exist in VHDL?. There is a statement called the process statement that contains only sequential statements. The process statement is itself a concurrent statement. A process statement can exist in an architecture and define regions in the architecture where all statements are sequential. A process statement has a declaration section and a statement part. In the declaration section, types, variables, constants, subprograms, and so on can be declared. The statement part contains only sequential statements. Sequential statements consist of CASE statements, IF THEN ELSE statements, LOOP statements, and so on.

4 Difference between c program and vhdl program?
There are 4 main differences between C programming and VHDL programming. C is a mid-level language, while VHDL is a hardware description language. C can handle one type of instruction, while VHDL can handle two. C does not require as much resource usage as VHDL. C can be written only with logical thinking, but a VHDL programmer must understand hardware circuits.
What are the data used in VHDL?
VHDL is a hardware description language which is used to describe digital circuits or systems. The data involved digital systems is logical data i. e. 0 or 1. Hence, VHDL uses logical data as input and provides the same type of data in output.
What is the VHDL code for half adder dataflow?
Half adder is a combinational circuit which can add two bits. It contains two inputs and two outputs. The same is implemented in entity declaration of VHDL program. The outputs are related to inputs as follows: SUM output is obtained by XORing the inputs and CARRY output is obtained by ANDing the inputs i. e. multiplication. The VHDL code for half adder using data flow model is given below: library IEEE; use IEEE.STD_LOGIC_1164.ALL; use IEEE.STD_LOGIC_ARITH.ALL; use IEEE.STD_LOGIC_UNSIGNED.ALL; entity had is Port ( a : in STD_LOGIC; b : in STD_LOGIC; s : out STD_LOGIC; c : out STD_LOGIC); end had; architecture df of had is begin s<= a xor b; c<= a and b; end df;
What is difference between hardware language and software language?
in my opinion hardware language is actually that which is easily understandable by hardware and that is machine language (depends on binary notation 0,1) and software language is used to make applications which is high level language. c#, c++, etc
What is tha full form of 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 as ASICs and FPGAs as well as conventional digital circuits. VHDL is an international standard, regulated by the IEEE. Simulation and synthesis are the two main kinds of tools which operate on the VHDL language. VHDL allows designs to be described using any methodology - top down, bottom up or middle out! VHDL can be used to describe hardware at the gate level or in a more abstract way.
