Introduction: In VLSI agreement send off, imperfection tolerance technique has been a vital ara of research. It is right off possible to make an integrated system on a chip by complecting a large number of dissimilar elements like processor and memory cell. Entire VLSI system design divided into two main approach Front end design and Backend design. In frontend design, we deal with digital technology and we whitethorn face some logical gaolbreak .but in backend design, we whitethorn face various hardware design faults. Mainly at that place are two approaches take in adopted for stain Tolerance - Architectural and Algorithmic. Algorithmic approaches towards fault tolerance are very complex and increase with the complexity of the problem. In new-fangled times, Architectural approaches are arriving at popularity because it does not need to take in in mind the complexity of the algorithm and also payable to its comfort of implementation.
In this article I am on the job(p) on Architectural design of Fault tolerance ALU system and using Triple Modular Redundancy. This technique however plain requires the adding together of substantial overhead through simple common chord replication of the processing elements.
Materials and Methods: There are many marionettes obtainable for scheming layouts of circuits like cadence-virtuoso, tanner, micro cabbage etc. I am by means of micro wind tool to execute a fault tolerant ALU. Micro wind tool is one of the most excellent tool for designing layouts design. By this tool you be able to also play the power utilization, graph between voltage and current and guck current value.
First I implement three ALU and machine-accessible them to the majority voter circuit. This majority voter circuit gives the fault free output of these ALUs. This majority voter circuit whole works on these phenomena.
If ALU1=ALU2 and ALU1?ALU3 then output=ALU1.
