Fpga Based Implementation of Bist Controller Using Different Approaches

Abstract

 Abstract—Testing of integrated circuits (IC's) is of crucial importance to ensure a high level of quality in product functionality in both commercially and privately produced products. Due to complex systems, its very difficult to test it. One solution to this problem is to add logic to the IC so that it can test itself. This is referred to as Built in self Test (BIST). In this work, we are designing BIST controller which will detect and correct errors while computing greatest common divisor (gcd) of two non-negative integers using two approaches i.e Euclid's algorithm and Stein's algorithm and comparing the results of both approaches , that we are using in this work. The most efficient way that will come can use for the applications for finding gcd.
