WebMar 4, 2024 · covergroup CG (ref bit condition, bit [2: 0] cp1) @ (posedge clk iff condition); Both condition and cp1 will now be passed by reference. The iff construct in a covergroup, coverpoint, or bins construct does not control the existence of an instance of a covergroup, coverpoint, it only gates the sampling of the bins. ... Webname. Expressions such as (clk && gating_signal) and (clk iff gating_signal) can be used to represent a gated clock. Other more complex expressions are possible. However, in order to ensure proper behavior of the system and conform as closely as possible to truly cycle-based semantics, the signals in a clock

A covergroup can contain one or more coverage points. A coverage point can be an integral variable or an integral expression. Each coverage point is associated with “bin”.On each sample clock simulator will increment the associated bin value.
