Abstract

The small power plan has turned in a high-performance Very Large Scale Integration (VLSI) model into one of the greatest challenges. The energy expended in the test mode has been found to be often much higher than in normal mode. This project aims mainly for the creation of an effective RAM based on MGDI and a low power Test Pattern Generator. LFSR (Linear Feedback Shift Register) is commonly employed in various Built in Self-Test (BIST), cryptography applications to generate pseudo-random numbers. Its theory discusses the possibilities of reducing energy during research applications on VLSI complementary metal oxide (CMOS) systems as power consumption during tests remains higher in contrast to normal operation. By selectively choosing the appropriate reversible gates for RAM design, this concept will be useful for low density and low power applications. A novel design of these 16*8 RAM architecture is designed with modified Gate Diffusion Technique for further improvement of area and power. Development of Low Transition Test Pattern Generators (TPGs) remains a common way of reducing consumption of power. In the Linear Feedback Shift Register with Low Density Modified Low Transition Low Power (LDMLTLP), dissipation of power during the experiment is minimized by lowering the switching operation between successive test vectors in contrast to two subsequent test vectors. Further power is reduced by using clock splitting technique
