The signal integrity design and simulation of triple modular redundant (TMR) computer

This paper analyzes the problem of Signal Integrity in the design of high speed communication between modules of Triple Modular Redundant(TMR) computer, from the detrimental effect caused by Reflection and Simultaneous Switching Noise (SSN). And, the simulation with the whole computer is tested and verified. Then, the design of TMR computer is improved by the simulation. This paper proposes solutions from the layout, circuit design and signal link, etc. And the solutions are tested and verified. Its results show that the improvement effect is obvious and improve the stability and reliability of the TMR computer and meet the needs of signal integrity for the high speed communication modules of Triple Modular Redundant (TMR) Computer.
