Our automaton is capable, like Langton's automaton and with comparable complexity, of simple self-replication, but it also provides (at the cost, naturally, of increased complexity) the option of attaching to the automaton an executable program which will be duplicated and executed in each of ...
However, building such systems cost-effectively and in a predictable manner is a major engineering challenge. In this paper, we explore the state-of-the-art in engineering self-adaptive systems and identify potential improvements in the design process. Our most important finding is that in ...
Again, the energy cost associated with the interfacial stress and dislocation loops would be expected to give rise to this reduced footprint on the substrate. In summary, we have used X-ray BCDI to gain unique insight into the epitaxial growth of calcite crystals on organic SAMs, where this...

As no test stimulus is required and the test output is purendigital, low-cost and practical implementation of on-chip BIST structurenfor a PLL is possibleSeongwon KimSoma, M.IEEE Transactions on Circuits & Systems II Express BriefsKim, S. and Soma, M.: An all-digital built-in self-...
This article presents a very low-cost built-in selftest technique for PLLs specifically designed for fault detection. The methodology relies on exciting the PLL loop in one location via a pseudo-random signal with noise characteristics and observing the response from another location in the loop ...

Experimental results using National Semiconductor Corp.'s 0.25μm CMOS 900MHz PLL demonstrates low-cost and practical BIST solution. The area overhead is minimized by using the existing PLL circuitry for BIST structure. The test time is typically 12μsec, significantly faster than conventional ...
This paper presents a low-cost Built-In Self-Test (BIST) scheme,which is based on the principle of parity check code.The proposed circuit is consisted of a XOR network,a frequency decrease module,a BIST controller and a fault detector module.Different from the previous methods of PLL BIST,...
