VLSI DESIGN & IMPLEMENTATION OF ELECTRONIC AUTOMATION USING VHDL
In this project of “VLSI design and implementation of Electronic Automation using VHDL ” we design a complex digital circuit using the language VHDL (Very High Speed Integrated Circuit Hardware Description Language).
As it is not possible to design such a complex digital circuit (consisting of more than 30,000 logic gates) manually to implemen t the above application, we use VLSI Technology for the solution.
With this technology we can construct a very big digital circuit requiring more than one lakh logic gates in a single chip .
This is carried out (Designed) by Programming. Thus it is simple and easy
to modify the existing design (add more features) by changing the instructions alone in the program and not the hardw are.
This final program is edited, compiled, synthesised and choosing the proper device we simulate and see the result ( working of the IC that we have designed ) on the screen.
In an electronic automation, we built in several el ectronic tools into a single chip. For example, a magnitude comparator, code converter, All logic gates, Half adder, full adder etc.
To construct the total circuit with the available ICs we require more than 11
ICs. But using a single VLSI chip we are able to integrate all of them into
it. Thus the same IC can be used for any of the above applications any number of times.
Thus we don’t require a big PCB and more number of components to assemble.
