coverpoint Acovergroupcan contain one or more coverage points. Acoverpointspecifies an integral expression that is required to be covered. Evaluation of thecoverpointexpression happens when thecovergroupis sampled. The SystemVerilog coverage point can be optionally labeled with a colon:. The example show...
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/covered" when the variable reaches the corresponding values. So, the binfeatureBis...

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...
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. Example: Macro definition: Macro usage: Macro...
You can also add other non-random variables to the set of unique values which has the effect of excluding the values of those variables from the set of unique values. When randomized, this class generates a set of ten unique values excluding the values 0, 7 and 15. Complex coverpoint bin...
