Unformatted text preview: l 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 implement 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 hardware. This final program is edited, compiled, synthesized and using the proper device we simulate and see the result (working of the IC that we have designed) on the screen. In general we switch ON a motor, fill the tank and then we switch OFF the motor. It is common. Here neither the over flowing is prevented nor the dry run (motor working without pumping water) is prevented. This causes several losses, for example water itself due to overflow, power, motor gets heated due to dry run and coil burns away etc. All the above losses are prevented with the help of single VLSI chip which consists of a complex controller circuit that we design by programming in VHDL...
