Temperature is one of the major sources of delay variations which may cause timing violations. In this paper, an approach to temperature aware clock skew scheduling for a general class of sequential circuits is proposed. At first, an alternative ...

Post-Silicon clock-Skew Tuning (PSST) is a promising technology for improving performance-yield of VLSIs under process variations. On the other hand, the resultant circuit after PSST should be also robust for run-time timing variations due to the change ...

Carbon Nanotube Field Effect Transistors (CNTFETs) are attractive alternatives to MOSFET devices as CNTFETs benefit from higher on-current, better gate control and faster switching response. However CNTFET-based technologies suffer from higher process ...

New measurement system for characterizing within-die delay variations of individual standard cells is presented. The proposed measurement system are able to characterize rising and falling delay variations separately by directly measuring the input and ...

With the development of network multimedia technology, more and more real-time multimedia applications need to transmit information using multicast. The basis of multicast data transmission is to construct a multicast tree. The main problem concerning ...

One of the main challenges in all-IP networks is the development of suitable mobility solution. Mobile IP (MIP) presents the standard protocol used to support IP mobility. However, MIP is inadequate for real-time applications and inter-domain mobility (...

Traditionally, spare rows/columns have been used in two ways: either to replace too leaky cells to reduce leakage, or to substitute faulty cells to improve yield. In contrast, we first choose a higher threshold voltage (V_th) and/or gate-oxide thickness (...

As the feature size of VLSI becomes smaller, delay variations become a serious problem in VLSI. In this paper, we propose a novel class of robustness for a datapath against delay variations, which is named structural robustness against delay variation (...

QoS-support technology in networks is based on measuring QoS metrics which reflect a magnitude of stability and performance such as delay, delay variation, available bandwidth and packet error rate and so on. The measurement of one-way delay essentially ...

In this letter, we discuss the impact of intrinsic error in parasitic capacitance extraction programs which are commonly used in today's SoC design flows. Most of the extraction programs use pattern-matching methods which introduces an improvable error ...

As VLSI technology advances, delay variations will become more serious. Delay-insensitive asynchronous dual-rail circuits tolerate any delay variation, but their energy consumption is more than double that of the single-rail circuits because signal ...

A newly devised inductance-oscillator (iOSC) has been developed which evaluates inductance impact on on-chip wire delay. iOSC is a ring oscillator which is comprised of a set of wires each with different loop inductance and accurate on-chip counter. The ...

Several factors such as process variation, noises, and delay defects can degrade the reliabilities of a circuit. Traditional methods add a pessimistic timing margin to resolve delay variation problems. In this paper, instead of sacrificing the ...

A significant proportion of link bandwidth measurement methods are based on IP's ability to control the number of hops a packet can traverse along a route via the time-to-live (TTL) field of the IP header. A new delay variation based path model is ...

Multicast routing consists of a tree which is rooted at the source node and contains all the multicast destinations. We study the problem of constructing a multicast tree that satisfies end-to-end delay along the paths from the source to each ...

We propose a new method to improve the accuracy of the transition density for the estimation of delay dependent switching activities in combinational circuits. In the previous method, glitching sensitivity concept was defined and used to modify the ...

The ATM Forum has defined a new service category, called the available bit rate service (ABR), which is intended for applications requiring tightly constrained cell loss but no bound on the delay or delay variation. Appropriate traffic control schemes ...

We propose a new model for the performance analysis of an ATM switching fabric based on a single-buffered Banyan network. In this model, we use a three-state, i.e., "empty", "new" and "blocked" Markov chain model to describe the behavior of the buffer ...
