An operating system extension and an application level network access program are provided. The operating system extensions receives file system requests for remote files from the operating system that were issued according to a well-known application program interface. The operating system extension forwards the remote file system request to the network access program. The network access program reformats the request according to a well known application level network protocol extensions and sends it over a network to a remote computer.

We use an original tree-structured representation of arbitrary boolean expressions, more compact than classic disjunctive form, allowing fast symbolic manipulation and natural mapping onto silicon. This implementation of ALPS produces static CMOS layout using a cascode-switch style. We present measurements done on fabricated circuits. For a large class of functions, particularly semi-regular control logic, VLSI layout generated by ALPS compares favorably in speed and area to PLAS and Standard-Cell designs.

A key feature of the system is its extensibility. It provides a small set of powerful abstractions for design description that can easily be extended by users. The system also allows convenient graphical specification of layout generators, and has been used to produce several large VLSI chips. has resulted in an extensible system, one in which there is no distinction between built-in abstractions and user-defined ones and where new abstractions may be added easily, and. it has made graphical and textual descriptions symmetric and interchangeable, permitting the designer to freely intermix the two in a given design.

The system is highly extensible and provides a unified framework in which both basic and powerful layout generators coexist. Several major chips have been built using this system.

Its features include conceptual integrity, rich expressive power, and high extensibility. It forms the nucleus of a design analysis and synthesis system which has been used to design several major chips.

Introduction Traditional design capture systems are typically either schematic-based or text-based. Most of the schematic-based systems represent designs as static entities in which decisions such as the width of buses and the size of memories are fixed. thereby greatly ...
