Language barriers in hardware design?

This article presents a set of fundamental principles underlying HDLs and has critically analyzed VHDL, which is the leading HDL. While a significant body of VHDL reflects elegant design, it suffers from a number of serious flaws. The suggestions provided in this article for modifications to key syntactic and semantic constructs of VHDL will help ensure its continued success as the state-of-the-art HDL into the next century. HDLs are the key to understanding computer hardware and software and are involved from the conception of any new computer or hardware design to the final implementation and testing of the IC
