摘要: The modified Booth array multiplier is the most ubiquitous architecture in datapaths of either general purpose microprocessors or specialized Digital Signal Processors. Sequential fault testing for multipliers has never been proposed past. In this paper, we present two BIST architectures with respect to Realistic Cell Fault model (RS-CFM). first aims resolve test invalidation problem largest possible extent, while second one cost reduction. Both achieve very high sequential coverage and impose moderate hardware delay overhead. Simplified variations are also presented non-recoded signed multipliers. Thus, offer a universal solution that covers totality multipliers: recoded.
