    This paper is a brief introduction to the automation of the design of very-large-scale integrated circuits (VLSI). The field of design automation has grown so large in the last twenty years that a complete treatment would require an encyclopedia. What follows, therefore, is only a sketch of the history, state of the art, and current key problems of the automation of VLSI design. View full abstract»

  • Digitizing, layout, rule checking—The everyday tasks of chip designers

    Publication Year: 1983, Page(s):49 - 56
    Cited by:  Papers (2)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (749 KB)

    The layout phase is most critical in the design of integrated circuits (IC's) because of the cost of the phase itself, since it involves expensive tools and a large amount of human intervention, and also because of the consequences for production Cost. Several approaches are used that need more or less computer and/or man time. The compromise is difficult because of the number of parameters to be ... View full abstract»

    The complexity of the circuit that can fit on an integrated circuit (IC) chip has reached the level of a million transistors with the advent of Very-large-Scale Integration (VLSI). Several automatic synthesis systems have evolved that "aid" the human designer in managing this complexity. This paper surveys such efforts. The synthesis is viewed as the process of transforming a high-level design spe... View full abstract»

    The increasing complexity of integrated circuits demands improved design quality. For system developments with small- or medium-scale integrated circuits, successive steps of the design process are interconnected loosely. Therefore, design checks, tests, and even redesigns could be performed without affecting large fractions of the overall design. With large scale integration (LSI) and especially ...

  • Complex eigenfrequencies of axisymmetric perfectly conducting bodies: Radar spectroscopy

    Cited by:  Papers (13)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (214 KB)

    The T-matrix allows a decoupling of the azimuth modes of the cross section axisymmetric conducting bodies. An eigenfrequency secular equation reveals a splitting of the complex poles as a sphere is deformed into a spheroid or cylinder. A level scheme, similar to an energy-level diagram in optical spectroscopy, is now possible. View full abstract»

  • Complex-frequency poles and creeping-wave transients in electromagnetic-wave scattering

    The impulse response of conducting targets is characterized by complex-frequency poles and their residues, as emphasized in the Singularity Expansion Method. We show that residue sums over correctly chosen pole subseries synthesize first and higher creeping waves on a sphere and describe their multiple circumnavigations with their proper (group) velocity.

    A simplified theoretical model to explain a magnetic effect on a Gunn diode is presented. When a dc magnetic field is applied transversely to a Gunn diode, the oscillation frequency decreases. This phenomenon is explained using a concept of successive collisions of drift electrons with lattice with constant free path. View full abstract»

    It is shown that by representing sampled-data signals as functions of continuous time (as opposed to impulse trains and sequences), a simple and clear description becomes possible for systems in which the instants of sample occurrence are not synchronized among the various signals involved.

    Performance of soft decoded extremal self-dual codes of lengths 8 to 72 are obtained over the Gaussian channel. The results indicate that for decoded bit-error rates below 10-3, which is the main region of interest for coding application, substantial coding gains can be obtained by using extremal self-dual codes.
