Note varibles are mentioned as a.coverpoint Coverpoints are put together in a block.covergroup Multiple covergroups can be created to sample the same variables with different set of bins. binsare said to be "hit

Macro usage for coverpoint(s) If the DV engineer wants to cover walk0/walk1 pattern bins of multiple variables of same width, then he/she can create and use the macro for all such signals for which walk1/walk0 cover bins are required. ...
coverpoint m_x; coverpoint m_y; endgroup function new(); cov1 = new; endfunction endclass In this example, data members m_x and m_y of class xyz are sampled on every change of data member m_z. When a covergroup is defined within a class, and no explicit variables of that covergro...
