Use of a standard non-rad-hard digital cell library in the rad-hard design can be cost-effective solution for space applications. In this paper we demonstrate how flip-flop, as one most vulnerable cells, converted into flip-flop without modifying its internal structure. We present five variants Triple Modular Redundancy (TMR) flip-flop: baseline TMR latch-based True-Single Phase Clock (TSPC) sc...

the bender-gestalt test was given to thirty mentally-retarded psychiatric patients. the mean, standard deviation, and standard error were 56.73, 26.25, and 4.80 respectively. rotation was the most frequent major deviation which occurred in all the designs. design # 7 was the most difficult one to be reproduced in the sample. this design by itself, was subject to 47% of distortion, 79% of omissi...

The manufacturability of integrated circuits can be improved at design level by incorporating modifications in the structure of the IP components (cores, cells, memories) and of interconnections, as well as changes in the design methodology and flow. In this tutorial we will describe the types of design improvements that can be introduced in the design of large integrated circuits, and the pote...

Advances in semiconductor process and design technology enable the design of complex system chips. Traditional IC design, in which every circuit is designed from scratch and reuse is limited to standard-cell libraries, is more and more replaced by a design style based on embedding large reusable modules, the so-called cores. This core-based design poses a series of new challenges, especially in...
