Test generation for behavioral models with reconvergent fanout and feed-back
… this thesis, new methods to handle reconvergent fanout and feed-back during behavioral level test generation are proposed. These methods have been implemented - into a previously developed automatic test generator. The improved test generator was tested on five behavioral circuit models. For …

DC powerline communication system using a transmission line transformer for high degree of freedom applications
… impedance characteristics that allow for large fanout and high bandwidth. First the basic architecture of DC powerline communication is presented, followed by verification of the feasibility of using a DC power bus as a communication medium. A high-fanout modem is then designed using a Guanella …

Extending the Birkhoff-von Neumann switching strategy to multicast switching
… of the pattern's "conflict graph", in the no-fanout-splitting case. We construct examples to show that, if dynamic fanout splitting is excluded, there is no clear winner in terms of rate region among various fanout splitting strategies. The problem of deciding whether a given set of rates is …

Throughput analysis of input-queued packet switches : multicasting and speedup
… performance of multicast switches when the fanout is deterministic, and obtain precise analytical results which exactly match simulations. Finally we analyze the throughput of multicast switches when the fanout is random and find, somewhat surprisingly, that the throughput is lowest when the …

Timing verification and synthesis of circuits for delay fault testability
… due to redundancy, reconvergent fanout, and control signal constraints. The RTL descriptions help to prune the search space because only valid paths are considered.

Virtual forced splitting in multidimensional access methods
… to the loss of desirable properties like high fanout and low internode overlap. The K-D-B tree is an example of a structure in which one property, that of zero internode overlap, is provided at the expense of another, high fanout. Its approach to doing this, by forced splitting, is shared by a …

Automatic back annotation of timing into VHDL behavioral models
… The first class of circuits are combinational fanout free circuits in which the fanout of each process in the Process Model Graph is one. Combinational circuits in which outputs of the processes are fed in as input to more than one process are classified as Class 2 circuits. Sequential register …

Low-power giga-bit per second optoelectronic integrated circuits for two-dimensional smart-pixel arrays
… provide wide bandwidth, low loss, and high fanout as compared to traditional electrical interconnects. In the past years many high performance optoelectronic circuits have been demonstrated. However, most of them require complicated process and exotic devices. In order to make optical …

A formal model for behavioral test generation
… handling bus resolution functions, reconvergent fanout, and feedback loops during test generation is discussed. Two-phase testing, a testing strategy where a fault is detected using two consecutive test sequences, is introduced and 1s formally incorporated into the B-algorithm.

Fast Approximation Framework for Timing and Power Analysis of Ultra-Low-Voltage Circuits
… of a variety of design parameters such as fanout, transistor widths, et cetera. In addition, we also validate our framework for a range of sequential benchmark circuits.

Erbium-ytterbium-yttrium compounds for light emission at 1.54[mu]m
… strength after subsequent 3dB splits during fanout of the optical signal to different microprocessors. Erbium ions (Er3+) are an excellent candidate to provide amplification around [lambda] = 1.54[mu]m for optical telecommunications. Erbium-doped fiber amplifiers (EDFAs) have already enabled …

MANY-BODY ENTANGLEMENT DYNAMICS AND COMPUTATION IN QUANTUM SYSTEMS WITH POWER-LAW INTERACTIONS
… allows one to implement the unbounded fanout gate asymptotically faster than systems with local interactions. This result also implies the hardness of simulating the dynamics of long-range systems evolving for superlogarithmic times, and demonstrates the potential for insights from …

Towards All-Optical Circuit-Switched Datacenter Network Architectures with Low Energy and High Performance
… all-optical core. Shufflecast leverages small fanout, inexpensive, passive optical splitters to connect the Top-of-rack (ToR) switch ports, ensuring data-rate agnostic, low-power, physical-layer multicast. To address the second challenge, I propose OSSV: a combination of OCS-based core (between …

Electronica Devices and Interface Strategies for Nanotechnology
Evaporation of ultra-thin layers of refractory metals onto glass substrates represents a relatively simple method of fabricating discontinuous metal films. The utility of these films in nanotechnology is based on the ability to control their morphology. In this thesis, control of discontinuous …

Techniques for High Performance Matching
… GenSMatcher adopts a trie node with a fixed high-fanout and a varying span for each node depending on the data distribution. The layout of the trie node leverage cache and modern processor features such as SIMD instructions. To support arbitrary matching, we interpret arbitrary rules into three …
