Introduction to VHDL
•VHDL stands for VHSIC (Very High Speed Integrated
Circuits) Hardware Description Language.
•VLSI Industry Requirement:
Verification of Complex VLSI IC Design is is very difficult by
using PSPICE tool. The complexity of the IC made the
necessity of developing computer aided design tool to
verify functional as well as timing characteristic of VLSI ICs.
•Source of VHDL:
In the mid-1980’s the U.S. Department of Defense and the
IEEE sponsored the development of this hardware
description language with the goal to develop very highspeed integrated circuit.
