Implementation of BIST Technology using March-LR Algorithm

In modern times VLSI technology has greatly been increasing the circuit integration, which has led to high-capacity and high-density embedded memories to be implemented on a system chip. The result of which increases the problem of faults that is growing exponentially, thus testing of memories has a major role in the process of testing, detecting faults and to increase the overall quality. An effective method to test the memory modules is by using the BIST technology. The dominant test algorithm that is used in the BIST module is the March Algorithm, Here the implementation of March-LR Algorithm is done to design the tests for the realistic linked faults. In this paper Synchronous MBIST using March LR algorithm is simulated on Xilinx ISE 14.7, implemented on FPGA “SPARTAN-6” and synthesized using RTL compiler from Cadence.
