This paper proposes a novel scheme to manage capture power in a pinpoint manner for achieving guaranteed capture power safety, improved small-delay test capability, and minimal test cost impact in at-speed scan test generation. First, switching activity around each long path sensitized by a test vector is checked to characterize it as hot (with excessively-high switching activity), warm (with normal/functional...
We propose a hybrid fixed/dynamic downstream scheduling scheme for 1G-EPON and 10G-EPON which enables ONU sleep mode operation for more than 90% of the time, at minor delay performance penalty and independently of network traffic.
Experimental data on the propagation of streamers in mineral oil is important for the design of high-voltage systems in the power and pulsed-power industries. In the present study, breakdown voltages and pre-breakdown delay times were measured for planeparallel electrodes, and for two non-uniform electrode arrangements. For each geometry, the breakdown characteristics were determined for impulses...
At-speed scan testing is susceptible to yield loss risk due to power supply noise caused by excessive launch switching activity. This paper proposes a novel two-stage scheme, namely CTX (Clock-Gating-Based Test Relaxation and X-Filling), for reducing switching activity when test stimulus is launched. Test relaxation and X-filling are conducted (1) to make as many FFs inactive as possible by disabling...
In this paper, we study bandwidth management of a wireless/optical based access/metro network in support of voice and data services. For voice services, we use a finite state Markov Chain to estimate the blocking probability of voice circuits over an Adaptive modulation and coding wireless channel, as a function of the channel parameters. For data services, we evaluate a rate matching and a buffer...
