In this paper, a technique for weighted pseudo-random built-in self-test (BIST) of VLSI circuits is proposed, which uses special scan cells and a new weight selection algorithm to achieve low power dissipation. It is based on weighted pseudo-random scan testing in which only 3 weight values are used - 2 fixed values (0 or 1) and 1 random value (0.5). A new(More)
Low power consumption and radiation hardness are generally competing requirements for space electronics as well as many Earth-bound high reliability applications. Fault tolerance typically requires redundancy and reconfigurability to ensure correct functional operation in the presence of errors. However, this runs contrary to the requirement for reduced(More)
Our previous studies demonstrated that nicotine induces c-fos expression in the suprachiasmatic nucleus (SCN) of the rat during a narrow developmental window occurring in the perinatal period. We have extended these observations by showing that c-fos cannot be induced in the adult SCN by nicotine even during the subjective night, when phase shifts do occur.(More)
(Affiliations can be found after the references in the electronic version) ABSTRACT Aims. A transient astrophysical event observed in both gravitational wave (GW) and electromagnetic (EM) channels would yield rich scientific rewards. A first program initiating EM follow-ups to possible transient GW events has been developed and exercised by the LIGO and(More)
The proliferation of both Partially Depleted Silicon-On-Insulator (PD-SOI) technology and domino circuit styles has allowed for increases in circuit performance beyond that of scaling traditional bulk CMOS static circuits. However, interactions between dynamic circuit styles and PD-SOI complicate testing. This paper describes the issues of testing domino(More)
