Abstract: A low overhead dynamically reconfigurable shared scan-in test architecture is provided. This test architecture advantageously allows for changing scan inputs during the scan operation on a per shift basis. The flexibility of reconfiguring the scan input to scan chain mapping every shift cycle can advantageously reduce both test data volume and test application time.

Abstract translation: 提供了低开销动态可重配置的共享扫描测试架构。 该测试架构有利地允许在每次移动的扫描操作期间改变扫描输入。 重新配置扫描输入到每个移位周期扫描链映射的灵活性可以有利地减少测试数据量和测试应用时间。
