VHDL Tutorial - Northeastern University

VHDL arose out of the United States government’s Very High Speed Integrated Circuits (VHSIC) program. In the course of this program, it became clear that there was a need for a standard language for describing the structure and function of inte-grated circuits (ICs). Hence the VHSI C Hardware Description Language (VHDL) was

Proving Algorithm Correctness

proof by cases/enumeration proof by chain of i s proof by contradiction proof by contrapositive For any algorithm, we must prove that it always returns the desired output for all legal instances of the problem. For sorting, this means even if the input is already sorted or it contains repeated elements. Proof by Counterexample
