Abstract:

The high reliability of embryonics hardware is supported by the novel architecture of reconfigurable cellular array. During the application design process, research on the method to improve the reliability is scarce. In this paper, those factors adjustable by designer in the application process have been extracted out, which affect the reliability of embryonics hardware. In embryonic hardware, cell area will change in different cell granularity, which is followed by the change of cellular array reliability. To solve this problem, a new reliability model is proposed for the traditional reliability model does not have parameters to express the area change of cells. After the reliability analysis of examples, variation laws of cellular array reliability with different cell granularity are summarized, and a cell granularity optimization method is raised. Based on the method, designers can choose the optimal cell granularity without a complete design of cellular array.

Key words: embryonics hardware, reliability analysis, circuit optimization, cellular granularity, reconfigurable
