A novel floorplanning method is presented that models blocks as rectangular "balloon"s, which are gradually expanded to determine their shapes and placement. Unlike the existing approaches, which assume the floorplan to be a slicing structure or which never handle fixed-shaped blocks, this method can handle fixed-shaped blocks as well as variable-shaped(More)
A distributed processing system is described, which is dedicated to mdtilayer SOG routing. The system is constructed of global and detailed routers, each based on distinct rip-up and rerouting procedures, so as to be run on a computer network composed of a number of worlcstations. Several implementation results attained for jive-layer SOG are also shown to(More)
The paper presents a multi-matcher on-line signature verification system which fuses the verification scores in the pen-position parameter and the pen-movement angle parameter at the decision level. The pen-position parameter consists of horizontal, x, and vertical, y, coordinates, and the pen-movement angle parameter is derived from the pen-position(More)
This paper presents a practical CAD system application for layout and verification, resulting in producible full-cutom VLSI microcomputer chips. The CAD system supports three design methodologies--symbolic layout mixed with mask level layout, compaction as an optimizer, and fully automated verification. For the area optimization, the symbolic layout and(More)
STARC is developing an RTL-to-GDS2 design methodology for 32nm (and 28nm) system LSIs called STARCAD-CEL. The design methodology focuses on four key areas: low power design, variation aware design and design for manufacturability as well as design productivity. This paper examines several techniques we used to solve issues the in design of challenging,(More)
