VHDL

This blog aims to provide a clear and accurate definition of VHSIC Hardware Description Language (VHDL). It is primarily intended for students, tool implementers, and advanced users who seek a deeper understanding of the language and its practical applications.

VHSIC stands for Very High Speed Integrated Circuit. U.S. Department of Defense initiated the program of developing VHDL in the late 1970s to advance the development of high-speed, high-performance integrated circuits for military applications. As part of this initiative, the VHSIC Hardware Description Language (VHDL) was created in the early 1980s to describe and model the behavior of digital systems before actual fabrication.
