Very Large Integrated Circuit (VLSI) is a domain where the nano work has been done over millions of transistors and diode and even on other electronics components. Every electronics devices available in market definitely consist of tiny electronics component. Funnel shifter is one of the most important element in any macro electronics devices which is responsible to do logical shifting of binary bits. So, how to make it using electric software and do testing whether the function which has been applied to make this element is right or not that is described here.
