<p>A reconfigurable scan array structure (60) for providing greater flexibility in customizing scan configurations for post-manufacturing applications. The structure (60) includes multiple scan cell segments (62), programmable scan-mode control switches (66), and programmable scan configuration switches (72). The multiple scan cell segments (62) are arranged in an array (64). The programmable scan-mode control switches (66) are placed between same scan cells (68) on two neighboring scan cell segments (70) and enable fine-tuning custom scan configurations to maximize effectiveness and efficiency for individual applications and designs. The programmable scan configuration switches (72) are placed between two scan cell segments (62) on a same row (74) as well as the left and right sides (76,78) of the scan array structure (60) and provide access points into the array structure (60) by SIs, SOs, or MISRs, and other manufacturing-critical components as well as enabling many scan configurations.</p> |
