VHDL is a hardware description language. You can describe the hardware in three different ways using VHDL.
1. dataflow model
2. behavioral model
3. structural model
A virtual calculator can be implemented using VHDL. We call it VHDL calculator.
VHDL is a text based programming language.
VHDL provides conversion functions and resolution functions.
vhdl code for binary to Hexadecimal ?
vhdl code for ascending order of numbers
"&" operator is not synthesized by VHDL synthesis tool.
A function is a subprogram written in VHDL. This program can be called and used in other programs.
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.
In 2008, Accellera released VHDL 4.0 to the IEEE for balloting for inclusion in IEEE 1076-2008. The VHDL standard IEEE 1076-2008 was published in January 2009. Currently, IEEE 1076-2008 is the latest version of VHDL.
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.

basic gates like XOR already exist in VHDL.
