A realistic test sets compression method is proposed to effectively reduce test data volume and test application time during system-on-chip (SoC) scan testing, count compatible pattern run-length (CCPRL) coding method counts the consecutive number of the equal to or contrary to the retained patterns, it modifies the compatible code of variable-length pattern run-length (VPRL) coding rules and adds a count code block to replace original rules for increasing compression ratio. Next, the decoder architecture and the state diagram of finite state machine (FSM) are designed. In addition, the power model of test vectors is analyzed, and the power consumption of scanned-in vectors is roughly evaluated. The six largest ISCAS'89 benchmark circuits verify the proposed coding method has a shorter codeword. Experiment results shows that all compression ratios have been increased as much as possible, test data decompression is lossless, less test application time is consumed, yet the peak power and average power consumption of scanned-in test vector needs to be further improved for modern circuit scan testing.

To improve the performance of power consumption information collection system and to solve the problem of system capacity small and the problem of low data rate, combined with the characteristics of WiMAX technology, the 230MHz wireless communication network of Power consumption information collection system was proposed based on WiMAX; The function and working methods of the communications network was designed. Implementations applicable to power consumption information collection system's key technologies was proposed such as Time division duplex, carrier aggregation, Software-Defined Radio through experimental verification. The results show that the use of this kind of communication networks can improve the data transfer rate, meet the bandwidth requirement, improve the reliability of data transmission and system Capacity and meet the business requirements of power consumption information collection system.
