"Power-Aware Testing for Low-Power VLSI Circuits"

Abstract: Low power has become an uncomprisable design requirement for LSI circuits destined for mobile or IoT applications, and numerous hardware/software techniques have been developed for drastically reducing power dissipation in function mode. However, the testing of such low-power LSI circuits is increasingly becoming a severe challenge, especially for at-speed scan testing where a transition is launched at the output of a flip-flop and the corresponding circuit response is captured by a flip-flop within a functional clock cycle in order to test for delay defects. The culprit is excessively high test power compared with functional power, caused by the significant difference between test and functional data and clocking schemes. Excessive test power may cause die/package damage due to excessive heat as well as undue yield loss due to excessive power supply noise on path delay and/or clock trees, as illustrated in the following figure. As a result, it has become imperative to apply power-aware testing to low-power LSI circuits. In order words, low-power LSI circuits cannot be successfully realized without effective and efficient power-aware testing solutions. This paper will highlight three major test-power-induced problems (namely heat, false failures, clock stretch) and describe how to mitigate them with power-aware VLSI testing. Future research topics in this field will also be discussed.

"Microelectronic Nerve Bridge for Neural Signal Regeneration and Microelectronic Nerve Antimissile System for Neural Signal Block"

Abstract: In the world there are more than 100 million patients who suffer from different neural deseases such as stroke, Parkinson's disease (PD), cerebral palsy, spinal cord injury (SCI), and so on. Of those patients, two states of the neural signal are divided: interrupt or abnormal. For the interrupt state, we have conceptualized the technique called microelectronic nerve bridge (MENB), and for the abnormal state, the techinique called microelectronic nerve antimissile system (MENAS). The function of the MENB is to regenerate the interrupted neural signal and let the related neural function rebuilding, while function of the MENAS is to eliminate the abnormal neural signals and let the spastic muscle keep rest. In this talk, the principles, the system constructions, and the experimental results of both MENB and MENAS are given.

"The Algorithm and VLSI Architecture of a High Efficient Motion Estimation with Adaptive Search Range for HEVC Systems"

Abstract: This talk presents a novel algorithm and VLSI architecture of Motion Estimation (ME) for High Efficiency Video Coding (HEVC) systems. The proposed algorithm examines a much smaller set of search candidates and thus greatly reduces the computational complexity. Furthermore, in order to strike a balance between the quality of the Video and the efficiency of the system, this algorithm possesses the advantages that the number of search candidates is adaptive to the characteristic of the Video content. The simulation results show that, compared to the HM reference software, the proposed algorithm leads to a 96% reduction of search candidates with only 1.98% increment of average bitrate. Based on this algorithm, a hardware-efficient VLSI architecture of ME is designed and implemented with 90nm technology. The experimental results show that, occupying the area complexity of 274.5 kGE, the presented design achieves 60 frames per second (fps) with resolution of 3840×2160 at the frequency of 201 MHz. The proposed ME system enhances the hardware efficiency by at least 50% compared to the prior works.
