WebJul 7, 2024 · This chapter explores SystemVerilog functional coverage in detail. It discusses methodology components, covergroups, coverpoint, and various types of “bins” including binsof, intersect, cross, transition, wildcard, ignore_bins, illegal_bins, etc. The chapter also discusses sample/strobe methods and ways to query coverage. WebThe binsof operator is used to select a subset of bins from a coverpoint. But since you are selecting the entire coverpoint a, there's no difference between using binsof(b) or …
WebOct 10, 2024 · Download chapter PDF. Introduction: This chapter covers the entire “Functional Coverage” language. We will cover the following features in the upcoming sections. 1. covergroups and coverpoints for variables and expressions. 2. automatic as well as user-defined coverage bins. 3. “bins” for transition coverage. Webignore_bins unused_rd = binsof(rd) intersect {0};} // here rd{0} must be neglected because in read operation rd must only be 1 so no need to consider coverage report when rd = 0 //dout verified during reading operation hence cross these two!! endgroup: c ci; //instance of a covergroup is created here: integer i = 0; task write();
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.
