Scan-Chain Partition for High Test-Data Compressibility and Low Shift Power Under Routing Constraint

Sying-Jyan Wang, K.S.-M. Li, Shih-Cheng Chen, Huai-Yan Shiu, Yun-Lung Chu
2009 IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems  
In essence, this approach simply puts similar scan flip-flops in an adjacent part of a scan chain, which also helps to reduce shift power in the scan test process.  ...  Experimental results show that the proposed partition method can raise the compression rates of various compression schemes by more than 17%, and the average reduction in shift power is about 50%.  ...  Thus, scan cells in the same partition can be ordered to minimize routing length or to serve other purposes.  ...
