Tutorial A-A:
The IEEE Standard VHDL Synthesis Packages: IEEE Std 1076.3-1996

Speaker

Abstract

In this tutorial, we will provide a look at the two standard VHDL synthesis packages that recently became an IEEE standard. The tutorial will explain in-depth the types and the various subprograms that make up the two packages. The two packages, NUMERIC_BIT and NUMERIC_STD, are arithmetic packages directed specifically for providing portability of VHDL synthesis models. The package NUMERIC_BIT contains arithmetic operations based on the type BIT, while the package NUMERIC_STD contains arithmetic operations based on the type STD_LOGIC. The rationale behind the design of the packages will also be presented.

The tutorial will also provide practical application usage of the packages in synthesizable VHDL models. This will demosntrate the portability feature of models that use these synthesis packages. Examples such as counters, finite-state-machines that use these packages will also be shown.

Curriculum Vitae

J. Bhasker received the B.Tech. degree in electrical engineering and an M.Tech. degree in computer technology from Indian Institute of Technology, New Delhi in 1977 and 1982 respectively. He received the Ph.D. degree in computer and information sciences from University of Minnesota, Minneapolis in 1985.

He is currently a Distinguished Member of Technical Staff in the Design Automation Center at Bell Laboratories, Lucent Technologies, where he has worked on synthesis and HDLs for the past nine years. Earlier he was a principal research engineer in the Advanced Architecture and Design section of Honeywell Corporate Systems Development Division.

He has authored five books of which "A VHDL Primer" (Published Prentice Hall), and "A VHDL Synthesis Primer" (Published Star Galaxy Publishing) are the most popular books. He also has been a Technical Program Chair, served on the technical program committees and served as session chairs at various VHDL International conferences (VIUF). In addition, he has over twenty journal and conference publications.
