In … WebSampling coverage in SystemVerilog is defined for each covergroup as a logical event (e.g. positive edge of the sampling signal). Alternatively, SV covergroup may be implicitly sampled using the built-in sample () method. In cocotb-coverage, sampling is done each time when a function containing a coverage is called. sight activities ks1
