Below code can implement NAND gate in VHDL.
The code is written in behavioral model.
Library ieee;
use ieee.std_logic_1164.all;
Entity gates is
port (a,b : in std_logic; c : out std_logic);
end gates ;
architecture and1 of gates is
begin
process(a,b)
Begin
If (a=1 and b=1) then
C<='0';
Else
C<= '1';
End if;
End process;
End and1;

Is VHDL text or graphic programmed?
VHDL is a text based programming language.
Which operator cannot be synthesized by a VHDL synthesis tool?
"&" operator is not synthesized by VHDL synthesis tool.
Why function in VHDL?
A function is a subprogram written in VHDL. This program can be called and used in other programs.
What is meaning of Test Benches in VHDL?
After compiling a hardware description language like VHDL, it is required to apply inputs to the program in order to obtain out puts. Applying the inputs involves initial conditions. As the systems designed using VHDL are electronic, the initial conditions plays a vital role. Hence, all these conditions along with the information as to where the input is expected to change from 1 to 0 or 0 to 1 is provided to the VHDL program. This is done in the form of a wave or another VHDL program. These are called VHDL test benches. In other words, test benches are the means of applying inputs to VHDL program.
How to implement XOR gate in behavioral model of VHDL?

How many version of vhdl are there in xillinx product?
VHDL is a hardware description language. XILINX is an EDA tool. EDA tools, electronic design and automation tools, are used to implement the programs like VHDL or Verilog. VHDL has several versions. But all these are standardized by IEEE and they don't belong to XILINX. Several FPGAs and CPLDs are manufactured by XILINX.
What is VHDL calculators?
A virtual calculator can be implemented using VHDL. We call it VHDL calculator.
How to do a password using vhdl?
A VHDL program can be written to provide a password in the following ways.Using FPGA:Your program can be dumped into a FPGA. This works as per the program written. As the code is burned into it, the user can not see the code. Now, within your program you can have a conditional statement which serves as your password. For example,if (c=ramarav) then...................................................................Using CPLD:It also works in the similar manner.Using a GUI:We can implement a graphical user interface, but the easier way is to take the help of MATLAB tool. We can implement our VHDL code in MATLAB tool and it serves the purpose.
What is full form of vhdl?
vhdl-v stands for vhsic...that is very high speed integrated circuit...and hdl means hardware description language Introduction to VHDL Full form :- Very high-speed integrated circuit hardware description language INTRODUCTION: VHDL stands for very high-speed integrated circuit hardware description language. Which is one of the 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 programe. In 1983 IBM, Texas instruments and Intermetrics started to develop this language. In 1985 VHDL 7.2 version was released. In 1987 IEEE standardized the language. http://www.electronicsgyan.com/introvhdl.aspx
