Discuss about Constrained-Random Verification Methodology

Advent  of  constrained-random  verification  gives  verification  engineers  an  effective  method  to achieve coverage goals faster and also help find corner-case problems. It shifts emphasis from writing  an  enormous  number  of  directed  tests  to  writing  a  smaller  set  of  constrained-random scenarios that let the computer resources do the work. Coverage goals are achieved not by sheer weight of manual labor needed to hand-write directed tests however by the number of processors which can be utilized to run random seeds. This significantly reduces time required to achieve the coverage goals.
