Abstract:

The aim of this study is hardware implementation of the Entropy analysis. Designing and verifying entropy analysis is the major finding of this study aper. Entropy tells how much amount of data can be compressed. Entropy analysis plays a major role in scan based SoC testing. Size and complexity have been the major issues for current scenario of System-on-a-Chip (SoC) testing. Test data compression is a must for such cases. Entropy analysis is taken for both specified and unspecified bits (donít care bits). Unspecified bits are specified using Zero and One fill algorithms. The X-filling technique is applied for fixed to fixed codes. The proposed method is successfully tested on ISCAS89 benchmark circuits.
