WebAn automatically single bin will be created for each value of the coverpoint variable range. These are called automatic, or implicit, bins. For an “n” bit integral coverpoint variable, a 2^n number of automatic bins will get created. WebARC1: cover property (STANDBY_SLEEP_CMD5); B. Second Method: Cover groups. The functional coverage construct, “covergroup”, of SystemVerilog is used in this method. The covergroup construct is built by defining one or more cover points as well as one or more cross coverage targets between the cover points.
