time-of-flight diffraction method (tofd) is an amplitude-independent sizing method which is based on the measurement of time-of-flight of defect tip diffracted waves. although tofd can measure through-wall length of defect accurately, this method is not capable of measuring horizontal defect size. in this paper, a new tofd method for evaluating horizontal planar defects is presented. the finite...

The authors present a new routing model for over-the-cell channel routing. A graph theoretical algorithm is then proposed to solve the new problem. The algorithm has a complexity of O(nk2), where n is the number of nets and k is the number of columns in the channel. It achieved a routing area reduction of 71.5% for the PRIMARY 1 benchmark example from MCNC, using three-layer over-the-cell routi...
