What is the VHDL code to implement NAND gate in behavioral model?
Ramarav
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;

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 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.
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 VHDL calculators?
