Abstract We present an overview of Ruby, the latest generation of backside optical laser voltage probing (LVP) tools [1, 2]. Carrying over from the previous generation of IDS2700 systems, Ruby is capable of measuring waveforms up to 15GHz at low core voltages 0.500V and below. Several new optical capabilities are incorporated; these include a solid immersion lens (SIL) for improved imaging resolution [3] and a polarization difference probing (PDP) optical platform [4] for phase modulation detection. New developments involve Jitter Mitigation, a scheme that allows measurements of jittery signals from circuits that are internally driven by the IC’s onboard Phase Locked Loop (PLL). Additional timing features include a Hardware Phase-Locked Loop (HWPLL) scheme for improved locking of the LVP’s Mode-Locked Laser (MLL) to the tester clock as well as a clockless scheme to improve the LVP’s usefulness and user friendliness. This paper presents these new capabilities and compares these with those of the previous generation of LVP systems [5, 6].

East West

The end of East-West hostilities in 1991 brought to the fore of international relations, some issues that had hitherto either been ignored or trivialised. One of these is the phenomenon commonly referred to as globalisation, which is more or less a euphemism for westernisation. Like colonisation, globalisation is propelled not by any moral considerations or an abstract concept of humanitarianism, but by the more economic exigencies of finding reliable markets for the industrial goods and services of the developed world as well as ready sources of raw materials for the industries of the world’s major economic powers. For developing countries like Nigeria, where political leadership influences not only domestic policies but foreign policy as well, there is a compelling need to embrace the globalisation with cautious optimism. For one thing, globalisation is a powerful force for growth and development. For another, it is a process that presents both challenges and opportunities. Such opportunities, however, must be exploited against the background of a dynamic foreign policy that sees the welfare of Nigerians as its major objective.
