Gone are the days when huge computers made of vacuum tubes sat humming in entire dedicated rooms and could do about 360 multiplications of 10 digit numbers in a second. Though they were heralded as the fastest computing machines of that time, they surely don’t stand a chance when compared to the modern day machines.Since the invention of the first IC in the form of a Flip Flop by Jack Kilby in 1958, our ability to pack more and more transistors onto a single chip has doubled roughly every 18 months, in accordance with the Moore’s Law. The development of microelectronics spans a time which is even lesser than the average life expectancy of a human, and yet it has seen as many as four generations.
Power Optimization of Linear Feedback Shift Register (LFSR) for Low Power BIST
Abstract – This paper proposes a low power Linear Feedback Shift Register (LFSR) for Test Pattern Generation (TPG) technique with reducing power dissipation during testing. The correlations between the consecutive patterns are higher during normal mode during testing. The proposed approach uses the concept of reducing the transitions in the test pattern generated by…
