An high hierarchical verification platform Based on UVM

On the basis of general UVM verification platform, put forward a double hierarchical sequence design, database share, protocol module, events triggers to synchronize etc the technique to optimize platform, realize an high hierarchical UVM verification platform, overcame the hard in general UVM in multiple verification environment, having the higher the abstract level in verification, efficiently, transparent handles with pithiness, good reuse. Pass a platform, a script run, realize the function coverage rate 100%, testing dot coverage rate 100%. this method simplified the UVM test complexity, quickly test speed, reduced the latent mistake that artificial test bring.
