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. WebOct 8, 2024 · SystemVerilog’s covergroup, does not support the cross coverage between two different covergroups as clarified by Dave. No, the above code will not compile. The cross a1b1 from covergroup ab1 is used in the different covergroup ab1c1. The cross a1b1 is used in creating cross a1b1c1 in the covergroup ab1c1. Referencing is done in object ...
