In LSI and VLSI layout, certain categories of signal nets, e.g. critical nets, power buses and data buses, require special attention during routing. In data bus routing the goal is to maximize the commonality of the routing paths comprising the bus, without unnecessarily lengthening individual routing paths. A topological data bus router has been(More)
LTX is a minicomputer-based design system for large-scale integrated circuit chip layout which offers a flexible set of interactive and automatic procedures for translating a circuit connectivity description into a finished mask design. The system encompasses algorithms for two-dimensional placement, string placement, exploitation of equivalent terminals,(More)
The Hughes Automated Layout System (HAL) is intended to provide fast, accurate, and efficient layout of LSI/VLSI circuits. The HAL development plan calls for an evolutionary development in three phases, with each phase providing a usable design system. HAL(I) is limited to standard cell layout and is now operational. HAL(II), which will permit more complex(More)
BACKGROUND Watson's Theory of Caring and Caritas proposes that caring and love potentiate healing. Creating a profile of the characteristics of a "Caritas nurse" has implications for integrating caring and love into patient care, and measuring the impact of caring on patient and operational outcomes. METHODS This psychometric study examined the profile of(More)
Interactive computer aids for integrated circuit layout usually offer a choice between slow, high-precision plotters or fast, low-resolution interactive media. A system, called GRAFOS, has been designed, which attempts to overcome resolution limitations by the use of symbolic referencing. It employs a symbolic routing language through which both the(More)
