Buffer insertion is a popular technique to reduce the interconnect delay. The classic buffer insertion algorithm of van Ginneken has time complexity , where is the number of buffer positions. Lillis, Cheng and Lin extended van Ginneken’s algorithm to allow buffer types in time . For modern design libraries that contain hundreds of buffers, it is a serious challenge to balance the speed and perf...

Ray-tracing is one of the most researched areas in 3D photo-realistic image synthesis. We propose the T-BUFFER algorithm, which is a modification to the conventional ray-tracing algorithm and compares very favorably with it in terms of performance, which is achieved primarily through reduction in the number of unsuccessful intersection tests. Our major contribution is the integration of a shado...

The results of comparative DC simulation tests confirm that a proposed modification to the feedback circuit of a Flipped Voltage Follower (FVF), to produce a type of ‘Folded’ Flipped Voltage Follower (FFVF), is capable of maximising the linear DC operating range for given values of supply rail voltage and operating current.

Abstract— This paper presents a new tracking circuit design without standby leakage current issue for 2.5V/3.3V tolerant I/O buffer, which is suitable for the I/O cells in the mixedvoltage applications with different driving capabilities. One set of mixed-voltage I/O cell with the new proposed 2.5V/3.3V tolerant I/O buffer circuit has been designed and drawn in a 0.13-μm salicided CMOS process....

Many works have studied the negative impact of slow start on the performance of short transfers. Some works propose to accelerate the window increase during this phase in order to improve the performance especially on satellite links. Others propose to set the slow start threshold at the beginning of the connection to a more accurate value in order to avoid losses. But, these works didn’t accou...

Determining interdependencies and cascading failure modes in critical infrastructures is a complex problem that is exacerbated further by the diverging characteristics of the interconnected infrastructure types. Services in some types of infrastructure such as telecommunications or the electric grid are provided and consumed instantly. Others, notably oil and gas but also other infrastructures ...
