VHDL is not any software. It is a programming language. One should learn how to program using VHDL. The supporting software tools may be downloaded from some of the EDA Tools providers on trial basis. Aldec is providing the student version for free.
A virtual calculator can be implemented using VHDL. We call it VHDL calculator.
VHDL provides conversion functions and resolution functions.
VHDL is a text based programming language.
vhdl code for binary to Hexadecimal ?
vhdl code for ascending order of numbers
A function is a subprogram written in VHDL. This program can be called and used in other programs.
"&" operator is not synthesized by VHDL synthesis tool.
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.
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
basic gates like XOR already exist in VHDL.
