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. WebJan 12, 2016 · Which inverts it (so excludes everything the expression includes). There are various values of A which pair with particular values of B. I can express the values of B that are allowed via the binsof(b1) intersect(b2) construct and invert it to get the non-allowed …
